Below these are several numbered drawings. You must determine which lettered figure is embedded in each of the numbered drawings . 14. a. A b. B c. C d. D e. E Answer. a
 15. The principle on which a simple interest of Rs 55 will be obtained after 9 months at the rate of 11/3 % per annum is. a. Rs 1000 b. Rs 1500 c. Rs 2000 d. Rs 2500 Solution. Let the principal amount be Rs. P. Rate of interest = 11/3 % and time = 9/12 years. So, Simple interest = P × (11/300) × (9/12) = 55 P = (55 × 12 × 300) / (9 × 11) = Rs. 2000 Answer. c
 16. A sum of money becomes 3 times in 5 years. In how many years will the same sum become 6 times at the same rate of simple interest? a. 15 years b. 12.5 years c. 10 years d. 7.5 years Solution. Let principal amount be â‚¹ P and rate of interest be R per annum. Time of investment is 5 years. So, first we need to find R such that P × (1+5R) = 3 × P â‡¨ R = 2/5 = 0.4 or 40% Now, we need to find the number of years T such that, â‡¨ P × (1 + 0.4T) = 6 × P â‡¨ 1 + 0.4T = 6 â‡¨ T = 5/0.4 =  12.5 Answer. b
