Question

If the annual rate of simple interest increases from 10% to 12 1/2 %, a man's yearly
income increases by Rs.1250. His principal is:
a) 45,000
b) 50,000
c) 60,000
d) 65,000​

Answer 1

Answer:

b) is the correct answer

Rate - R =  12 1/2% - 10% = 2.5%

Time - T =  1  year

Simple interest - S.I = Rs. 1250

S.I = P x R x T/100

1250 = P x 2.5 x 1 / 100

P = 1250 x 100/ 2.5

P = 50,000
