AFCAT Model Paper 7

Given:
20% of A = 60% of B = 70% of C = 50% of D
Total Sum = Rs. 25440
Calculation:
According to the question
2A = 6B = 7C = 5D
⇒

2A=6B=7C=5D

210

⇒

2A

210

=

6B

210

=

7C

210

=

5D

210

⇒

A

105

=

B

35

=

C

30

=

D

42

Let the share of A, B, C and D is 105k, 35k, 30k and 42k, respectively.
⇒ 105k + 35k + 30k + 42k = 25,440
⇒ 212k = 25,440
⇒k=25,

440

212

⇒ k = 120
So, the share of C = 30k = ₹ 3,600
⇒ The share of D = 42k = ₹ 5040
According to question,
⇒ Increased share of C = 120% of 3,600 = ₹ 4320
⇒ Increased share of D = 105% of 5040 = ₹ 5292
∴ The ratio of increased share of C and D is = 4320 : 5292 = 40 : 49
