Question

What sum will amount to earn 406 as simple interest at 7/2%per annum in 29/4 years

Answer 1

Answer:

the sum is 1600.

Step-by-step explanation:

simple interest=I=p*(7/2)*(29/4) /100

given, I=406=p*(7*29)/800

then, p=(406*800)/(7*29)

p=1600

Answer 2

Answer:

Rs.1600.00

Step-by-step explanation:

we know Simple Interest = Principle(p) * Years (n) * Rate (r%)

Let x be the principle

so we have 406 = x *29/4 * 7/200

406 = x * 203/800

x = 406*800/203 = 1600 is the principle
