Question

in how many years rs.150 will produce the same interest at 8% as rs.800 prodce in 3 years at 9%?

Answer 1

Your answer is here


How many years rupees 150 will produce the same interest at 800 rupees produce in 3 years

So then

{Formula} =

S. I. = Price × Rate × Time ÷ 100

1st We calculate 800 rupees interest

S. I. = 800 × 9 × 3 ÷ 100

S. I. = 216


Simple intrest of 800 rupees is 216. And now we want to know how many years rs.150 will produce the same interest at 8 %.

So

{Formula} =

S. I. = Price × Rate × Time ÷ 100


But we want time then :

Time = S. I. × 100 ÷ price × rate

Time = 216 × 100 ÷ 150 × 8

Time = 18



Your answer is 18 years.
