Simple Interest Worksheet



Practicing questions on simple interest worksheet help the children to calculate simple interest (S.I.) and amount (A). We will recapitulate the same and know more about it and practice more questions given in the worksheet on simple interest.

While solving the questions on simple interest worksheet we need to remember; 
the formula for calculating simple interest (S.I.) = (P × R × T)/100 and, formula for calculating amount (A) = P + I

1. Find the simple interest and amount in each of the following:

(a) P = $1800       R = 5%        T = 1 year

(b) P = $2600       R = 12%       T = 3 years

(c) P = $3125       R = 15%       T = 73 days

(d) P = $5660       R = 11%       T = 9 months

(e) P = $180        R = 3%         T = 1¹/₄ year

13. Find the simple interest at the rate of 5% p.a. for 3 years on that principal which in 4 years, 8 months at the rate of 5% p.a. gives $1200 as simple interest.

14. At what rate per cent per annum will $4000 yield an interest of $410 in 2 years?

15. Simple interest on a certain sum is ¹⁶/₂₅ of the sum. Find the rate per cent and time if both are numerically equal. [Hint: (T = R), P = x, S.I. = ¹⁶/₂₅ x]

16. Simple interest on a sum of money at the end of 5 years is ⁴/₅ of the sum itself. Find the rate per cent p.a.
