Q:

A + B + C = 5625

4B + B = 5625

B = 1125

Also A + C = 4B = 4 x 1125 = 4500

Also

B = 2A - C

2A - C = 1125

Now solving A+C = 4500 and 2A-C = 1125

Then A = 1875 and C = 2625

A-B = 1875 - 1125 = Rs. 750

Q:

A) 10 | B) 15 |

C) 20 | D) 30 |

Answer & Explanation
Answer: D) 30

Explanation:

Explanation:

Let the three parts M, N, O.

Then, M:N = 2:3 and N:O = 5:8

= (5 x 3/5) : (8 x 3/5) = 3:24/5

M:N:O = 2:3:24/5

= 10:15:24 => N = 98 x 15/49 = 30.
