Syam invests apart of Rs. 12,000 in 12% stock at Rs. 120 and the remainder in 15% stock at Rs. 125. It his total dividend per annum is Rs. 1360, how much does he invest in 12% stock at Rs. 120?


A) 4000

B) 5000

C) 6000

D) 7000

E) 7500

Answer:

Option A

Explanation:

Let investment in 12% stock be Rs. x
Then investment in 15% stock = Rs. 12000 - x

(12/ 120) x X + (15/ 125) x ( 1200 - X) = 1360

=> (X/10) + (3/25) (12000-X) = 1360 => 5x + 72000 - 6x = 1360x50

x = 72000 - 68000 =>x = Rs. 4000
