{20 – [7 – (3 -2)] + 1/3 (4.2)} / 1.4 = ________?

{20 – [7 – (3 -2)] + 1/3 (4.2)} / 1.4 = ________?

A. 11
B. 12
C. 14
D. 19
Explanation:
{20 – [7 – (3 -2)] + 1/3 (4.2)} / 1.4
=> [20 – (7 – 1) + 1.4] / 1.4
=> (20 – 6 + 1.4)/1.4 = 10 + 1 = 11

A man saves Rs. 200 at the end of each year and lends the money at 5% compound interest. How much will it become at the end of 3 years?

A man saves Rs. 200 at the end of each year and lends the money at 5% compound interest. How much will it become at the end of 3 years?

A. Rs. 565.25
B. Rs. 635
C. Rs. 662.02
D. Rs. 666.50
Explanation:
Amount = [200(1 + 5/100)3 + 200(1 + 5/100)2 + 200(1 + 5/100)]
= [200 * 21/20(21/20 * 21/20 + 21/20 + 1)] = Rs. 662.02

What will be the ratio of simple interest earned by certain amount at the same rate of interest for 6 years and that for 9 years ?

What will be the ratio of simple interest earned by certain amount at the same rate of interest for 6 years and that for 9 years ?

A. 1 : 3
B. 1 : 4
C. 2 : 3
D. Data inadequate
Let the principal be P and rate of interest be R%. So Required ratio = [(P x R x 6/100) / (13 x R x 9/100)] = 6PR/9PR = 6/9 = 2 : 3

A. 44
B. 55
C. 66
D. 77
Let the numbers be a, b and c. a+b+c = 172 a:b = 8:11 b:c = 5:7 11a = 8b a = 8b/11 7b = 5c c = 7b/5 (8b/11)+b+(7b/5) = 172 40b+55b+77b = 172*55 172b = 172*55 b=55
