Answer»

Radius of ball which is melted = 3cm

Radius of first formed ball = 1.5 cmRadius of second formed ball = 2 cmLet Radius of third formed ball = r cm

Volume of large ball = sum of volume of 3 formed balls⇒4π/3 × 3³ = 4π/3(1.5³ + 2³ + r³)⇒ 3³ =1.5³ + 2³ + r³⇒ 27 = 3.375 + 8 + r³⇒ r³ = 27 - 8 - 3.375 = 15.625⇒ r = ∛15.625⇒ r = 2.5cm

∴Radius of third ball is 2.5cm

6. An article marked at800 is sold at a discountof 10%. Find its cost price if the dealer makesa profit of 20%. Also find the profit per cent ifno discount had been allowed

Answer»

Discount of 10% on marked price=800*10%=80

Selling price=800-80=720

The dealer makes a profit of 20% means is selling the article at 120%.

120%=720

1%=6

Hence, 100%=600

Thus, the cost price of article= 600

If no discount allowed,

Selling price will become 800

Profit= SP-CP= 800-600=200

Profit percent=(200/600)*100=33.33%

Therefore, the profit percent when no discount allowed=33.33%

133. A shopkeeper sold a TV set for *17940, with adiscount of 8% and gained 19.6%. If no discount isallowed, then what will be his gain per cent?

Answer»

Discount = 8% & S.P.= Rs.17,940

Therefore, M.P. = 17940/0.92 = Rs.19500

Now, gain % = 19.6%

=> C.P. = 17940/1196 = Rs.15000

MP - CP = Rs.4500

Hence gain % = (4500/15000) ×100 = 30%

13, Theratioofdimensionsofacuboidalboxis2:3:4OX 1S 2:3:The difference between the cost of wrapping thebox at the rate of74 per square meter andper square meter is R 416. Find the dimensions ofthe cuboidal box.[Board Term II, Set-RQTZFBW, 2016]

Answer»

Since the ratio of a cuboidal box are 2:3:4.So suppose the dimensions of cuboid box are 2x, 3x and 4x respectively.So total surface area of box =2(2x*3x+3x*4x+2x*4x)=52x^2Cost of wrapping the box at rate of Rs.4.50 per square metre =52x^2*4.50=234x^2And cost of wrapping the box at rate of Rs. 4 per square metre =5x^2*4=208x^2Now according to the question we have;234x^2-208x^2=41626x^2=416x^2=16x=4So dimensions of cuboidal box are(2*4),(3*4),(4*4)Therefore dimensions of box are 8 m, 12 m, and 16 m.
