Answer 1

Answer:

(d) 1800

Step-by-step explanation:

Define x:

Let the capital be C

1/5 of the capital at 5% p.a.

Interest earned = 0.05 x (1/5)C = (1/100)C

1/6 of the capital at 6% p.a.

Interest earned = 0.06 x (1/6)C = (1/100)C

The rest at 10% p.a.

The rest = 1 - 1/5 - 1/6 = 19/30

Interest = 0.1 x (19/30)C = (19/300)C

Total amount received is Rs 150

(1/100)C + (1/100)C +  (19/300)C = 150

(1/12)C = 150

C = 150 ÷ 1/12

C = Rs 1800

Answer: The capital is (d) Rs 1800
