Answer 1

Step-by-step explanation:

A sum of money doubles itself in 16 years at simple interest. annual rate will be

• So let the sum of money be Rs 100
• Now in 16 years the sum doubles so we get Rs 100 as Rs 200
• Interest in 16 years is Rs 100
• Therefore in 1 year it will be 100 / 16
•                                                 = 25 / 4
•                                                 = 6 1/4
•                                                 = Rs 6.25
• So the rate percent per annum is 6.25%
•                        OR
• Now Simple Interest = Amount – Sum
• So the sum is P and the amount after 16 years will be 2P
•             So S.I = 2P – P
•                       = P
•               So P = P x R x 16 / 100
•              Or 16 R = 100
•              Or R = 100 / 16
•                R = 25 / 4
•              R = 6 ¼%
