Question
Ravi lends Rs. 16000 to two of his friends. He gives
Rs.8000 to the first at 15% p.a. simple interest. Ravi wants to make a profit of 20% on the whole. The simple interest rate at which he should lend the remaining sum of money to the second friend isSolution
Let Ravi lend the sum at x% rate to the second friend. According to the question, 15% × 8000 + x% of 8000 = 20% of 16000 ⇒ 15 × 80 + 80x = 20 × 160 ⇒ 80x = 3200 – 1200 ⇒ 80x = 2000 ⇒ x = 25 Hence, the required rate of interest is 25% p.a.
40.22 of 249.98% + 459.99 ÷ 23.18 = ?
583.9 + 1519.98 - 445.21 = 1150.011 + ?
? = 41.92% of 49.96% of (45.07 1.97 – 4.98 2.03 )
14.12 × 21.98 + 25.22% of 195.99 = ? × 50.9
