Question

The ratio of incomes of C and D is 3 : 2. Ratio of income of D and E is 5 : 4. If one-third of C’s income is Rs 4000 more than the half of E’s income, then what is the D’s income (in Rs)?

A) 40000 B) 43000 C) 50000 D) 60000

Answer 1

Answer:

40,000

Step-by-step explanation:

Ratio of income of C and D = 3 ? 2 = 15 ? 10

Also,

Ratio of income of D and E = 5 ? 4 = 10 ? 2

Let income of C, D and E be 15x, 10x and 8x respectively

According to the question

⇒ (1/3) of 15x = (1/2) of 8x + 4000

⇒ 5x = 4x + 4000

⇒ x = 4000

∴ D’s income = 10x = 10 × 4000 = 40,000
