( 100 10000×5×1 )=Rs.500 Amount at the end of second quarter =Rs.10500+Rs.525=Rs.11025 Principal for the third quarter =Rs.11025 Interest for the third quarter = Rs.( 100 11025×5×1 )=Rs.551.25 Amount at the end of the third quarter =Rs.11025++Rs.551.25=Rs.11576.25 Principal for the FOURTH quarter Rs.11576.25 Interest for the fourth quarter = Rs.( 100 11576.25×5×1 )=Rs.578.8125 Amount at the end of the fourth quarter =Rs.11576.25+Rs.578.8125=Rs.12155.0625 Compound interest =Rs.12155.0625−Rs.10000=Rs.2155.0625 Step-by-step explanation:

1.

Find the amount on rs. 10,000 for 1 year at the rate of 20% annum compounded half yearly

Answer»

Answer:We have Rate of INTEREST = 20% per annum =

4

20

=5% per quarter

Time = 1 year = 4 quarters

Principal for the first quarter = Rs. 10000

Interest for the first quarter = Rs.(

100

10000×5×1

)=Rs.500

AMOUNT at the end of first quarter =Rs.10000+Rs.500=Rs.10500

Principal for the second quarter =Rs.10500

Interest for the second quarter = Rs. (

100

10000×5×1

)=Rs.500

Amount at the end of second quarter =Rs.10500+Rs.525=Rs.11025

Principal for the third quarter =Rs.11025

Interest for the third quarter = Rs.(

100

11025×5×1

)=Rs.551.25

Amount at the end of the third quarter =Rs.11025++Rs.551.25=Rs.11576.25

Principal for the FOURTH quarter Rs.11576.25

Interest for the fourth quarter = Rs.(

100

11576.25×5×1

)=Rs.578.8125

Amount at the end of the fourth quarter =Rs.11576.25+Rs.578.8125=Rs.12155.0625

Compound interest =Rs.12155.0625−Rs.10000=Rs.2155.0625

2.	Choose two consecutive numbers whose product exceeds the square of the smaller number by 9
Answer» Answer: 9,10 Step-by-step EXPLANATION: let X and x+1 be the 2 consecutive no.s given that, x(x+1) = x²+9 => x²+x = x²+9 => x = 9 so, the 2 no.s are 9,9+1 ie, 9 and 10 Verification product of 9 and 10 = 910 = 90 ----------- (1) SQUARE of the SMALLER no. = 99 = 81 => product = sqr(smaller NUMBER) + 9 hence verified

2.

Choose two consecutive numbers whose product exceeds the square of the smaller number by 9

Answer»

Answer:

9,10

Step-by-step EXPLANATION:

let X and x+1 be the 2 consecutive no.s

given that, x(x+1) = x²+9

=> x²+x = x²+9

=> x = 9

so, the 2 no.s are 9,9+1

ie, 9 and 10

Verification

product of 9 and 10 = 9*10 = 90 ----------- (1)

SQUARE of the SMALLER no. = 9*9 = 81

=> product = sqr(smaller NUMBER) + 9

hence verified

(16.The mean of 200 items was 50. Later on, itwas discovered that two items were misreadas 92 and 8 instead of 192 and 88. Find thecorrect mean

Answer»

ANSWER:-

Since,

MEAN of 200 ITEMS = 50

No.ofitems

sumof200items

=mean

sum of 200 items = mean of x no of items

50×200=10,000

wrong sum of 200 items = 10,000

Correct sum = 10,000+192+88-92-8

= 10,280-100

=10,180

∴ correct mean =

200

10,180

= 50.9
