|
Answer» C.P of 100 hens = RS. 8000 COST of one hen = 8000100 Rs. 80 C.P of 20 hens = Rs (80*20) = Rs. 1600 GAIN = 5% S.P = 105100×1600 = Rs. 1680 C.P of 80hens = Rs.(80*80) = Rs. 6400 Gain on 80 hens – C.P 80 hens Gain on 100 hens = gain on 80 hens + gain on 20 hens = 80+ S.P of 80 hens – 6400 S.P of 80 hens = Rs (1600+6400-80) S.P of 80 hens = Rs. 7920 Gain on 80 hens = S.P of 80 hens – C.P of 80 hens = Rs. (792-6400) = Rs. 1520 Gain % 80 hens = 15206400×100 = 23.75% Therefore, Toshiba gained 23.75% on 80 hens. C.P of 100 hens = RS. 8000 Cost of one hen = 8000100 Rs. 80 C.P of 20 hens = Rs (80*20) = Rs. 1600 Gain = 5% S.P = 105100×1600 = Rs. 1680 C.P of 80hens = Rs.(80*80) = Rs. 6400 Gain on 80 hens – C.P 80 hens Gain on 100 hens = gain on 80 hens + gain on 20 hens = 80+ S.P of 80 hens – 6400 S.P of 80 hens = Rs (1600+6400-80) S.P of 80 hens = Rs. 7920 Gain on 80 hens = S.P of 80 hens – C.P of 80 hens = Rs. (792-6400) = Rs. 1520 Gain % 80 hens = 15206400×100 = 23.75% Therefore, Toshiba gained 23.75% on 80 hens. |

The Difference Between Two Selling Pieces Of A Shirt At A Profit Of 4 % And 5% Is Rs.6. Find: (i) P Of The Shirt (ii) The Two Selling Prices Of The Shirt |
|
Answer» Let the C.P of both the shirt be RS. X For 1 shirt PROFIT = 4% Profit% = Rs. 0.04x S.P = Rs.1.04x For 2 shirt profit = 5% Profit% = Rs. 0.05x S.P = Rs.1.05x It is given that the DIFFERENCE between their profits is Rs.6 So, 1.05x-1.04x = 6 = x = Rs.600 Thus, C.P = Rs.600 S.P of 1 shirt 1 = Rs.1.04x = Rs. 1.04(600)= Rs. 624 S.P of 1 shirt 2 = Rs.1.05x = Rs. 1.05(600)= Rs. 630 Let the C.P of both the shirt be RS. X For 1 shirt profit = 4% Profit% = Rs. 0.04x S.P = Rs.1.04x For 2 shirt profit = 5% Profit% = Rs. 0.05x S.P = Rs.1.05x It is given that the difference between their profits is Rs.6 So, 1.05x-1.04x = 6 = x = Rs.600 Thus, C.P = Rs.600 S.P of 1 shirt 1 = Rs.1.04x = Rs. 1.04(600)= Rs. 624 S.P of 1 shirt 2 = Rs.1.05x = Rs. 1.05(600)= Rs. 630 |

Shabana Bought 16 Dozens Ball Pens And Sold Them At A Loss Of To S.p Of 8 Ball Pens. Find: (i) Her Loss Percent (ii) P Of 1 Dozen Ball Pens, If She Purchased These 16 Dozens Ball Pens For Rs.576 |
|
Answer» (i) Number of pens bought = 16(12) = 192 Let S.P of one pen be Rs. x Therefore, S.P of 192 pens = 192x C.P of 8 pens = Rs. 8X It is given that S.P of 8 pens is equal to the loss on SELLING 192 pens. Therefore, loss= Rs.8x C.P of 192 pens = Rs 576 Loss = C.P –S.P = 8x = 576 – 192x200 = 576 x = 576200 =x= 2.88 Therefore, loss= RS.23.04 Loss% = 4% (II) P of 1 pen = Rs.2.88 Therefore, S.P of 1 dozen pens = 12x = 12(2.88) = Rs.34.56 (i) Number of pens bought = 16(12) = 192 Let S.P of one pen be Rs. x Therefore, S.P of 192 pens = 192x C.P of 8 pens = Rs. 8x It is given that S.P of 8 pens is equal to the loss on selling 192 pens. Therefore, loss= Rs.8x C.P of 192 pens = Rs 576 Loss = C.P –S.P = 8x = 576 – 192x200 = 576 x = 576200 =x= 2.88 Therefore, loss= RS.23.04 Loss% = 4% (ii) P of 1 pen = Rs.2.88 Therefore, S.P of 1 dozen pens = 12x = 12(2.88) = Rs.34.56 |

A Tricycle Is Sold At A Gain Of 16%. Had It Been Sold For Rs.100 More, The Gain Would Have Been 20%. Find The C.p Of The Tricycle ? |
|
Answer» Let the S.P of the tricycle be Rs. x Let the C.P of the tricycle be Rs. y Gain % = 16% Then we have, = x= y+ 16y100 = x = y+ 0.16y When S.P increases by Rs.100, we get = x+ 100 = y + 20 y 100 PUTTING x = 1.6y = 1.16y+100 = y+0.2y = 1.16y +100 = 1.2y = y = 2500 The C.P of the cycle is 2500 Thus, C.P of the tricycle is Rs. 2500. Let the S.P of the tricycle be Rs. x Let the C.P of the tricycle be Rs. y Gain % = 16% Then we have, = x= y+ 16y100 = x = y+ 0.16y When S.P increases by Rs.100, we get = x+ 100 = y + 20 y 100 Putting x = 1.6y = 1.16y+100 = y+0.2y = 1.16y +100 = 1.2y = y = 2500 The C.P of the cycle is 2500 Thus, C.P of the tricycle is Rs. 2500. |

Some Toffees Are Bought At A Rate Of 11 For Rs.10 And The Same Number At The Rate Of 9 For Rs.10. If The Whole Lot Is Sold At One Per Toffee, Find The Gain Or Loss Percent On The Whole Transaction. |
|
Answer» LET the total number of toffees bought be RS. X Let x2 at the rate of 11 are bought for Rs.10, Total money spent on toffees = 200x198 = 100x99 It is given that x toffees are sold at Re.1 per toffee. Therefore, the selling price of x toffees = Rs. x(1) As C.P is more than S.P, it will be the loss. Loss= C.P-S.P = 100x99 – x = x99 Loss% = 1% The total loss on the WHOLE transaction would be 1% Let the total number of toffees bought be Rs. x Let x2 at the rate of 11 are bought for Rs.10, Total money spent on toffees = 200x198 = 100x99 It is given that x toffees are sold at Re.1 per toffee. Therefore, the selling price of x toffees = Rs. x(1) As C.P is more than S.P, it will be the loss. Loss= C.P-S.P = 100x99 – x = x99 Loss% = 1% The total loss on the whole transaction would be 1% |

A Man Sells An Article At A Profit Of 25%. If He Had Bought It At A 20% Less And Sold It For Rs.36.75 Less, He Would Have Gained 30%. Find The Cost Price Of The Article ? |
|
Answer» Let the C.P be the article be Rs. x Profit = 25% ORIGINAL S.P = x + 25100x = Rs. 5x4 If he purchased it at 20% less, C.P = x- 20100x = Rs. 4x5 He SOLD the article at Rs. 36.75 So, the selling price = Rs. 5x4 – 36.75 Given, that he would have gained 30% selling at that price. THEREFORE, gain% = S.P-C.P = 5x4 -36.75 – 4x5 = 25x−16x20 -36.75 So, gain % = 9x20-36.75- 4x5(100) = 18375x = 18375105 = x = 175 The cost price of the article is Rs. 175. Let the C.P be the article be Rs. x Profit = 25% Original S.P = x + 25100x = Rs. 5x4 If he purchased it at 20% less, C.P = x- 20100x = Rs. 4x5 He sold the article at Rs. 36.75 So, the selling price = Rs. 5x4 – 36.75 Given, that he would have gained 30% selling at that price. Therefore, gain% = S.P-C.P = 5x4 -36.75 – 4x5 = 25x−16x20 -36.75 So, gain % = 9x20-36.75- 4x5(100) = 18375x = 18375105 = x = 175 The cost price of the article is Rs. 175. |
