Jancy invested an amount of Rs. 9,000 at the rate of 10% p.a simple interest and another amount at the rate of 15% p.a. simple interest. The total interest earned at the end of one year on the total amount invested became 14% p.a. Find the total amount invested? Choose the correct option
A) 15800	B) 12800	C) 11800	D) 16800	E) 17800
Let the second amount be Rs. x. Then,   (9000 * 10 * 1)/100 + (x * 15 * 1)/100 = [(12000 + x) * 14 * 1] / 100   9000+ 15x= 16800 + 14x   x = 7800   Total investment = 10000 + 7800 = Rs. 17,800.Answer: 17800
