Solutions

S1. Ans.(a)
Sol. Let the initial investments of Vinod and Ankit be 2x and 3x, respectively.
As per the question,
(2x+ 10000)/3x = 3/2
4x + 20000 = 9x
∴ x = 4000
∴ Amount invested by Vinod = 2x = Rs. 8000.

S2. Ans.(c)
Sol. Ratio of their investments
= 50000 × 12: 90000 × 8 = 5: 6
∴ Amount received by Mr Jain
= (6/11) × 22000 = Rs. 12000.

S3. Ans.(C)
Let C’s share = Rs. x. Then
B’s share = Rs. x/2
And, A’s share = Rs. x/4
A: B:C = x/4:x/2:x=1:2:4
Hence, C’s share = Rs. (700)×(4/7) = Rs.400

S4. Ans.(d)
Sol. Suppose, B joins A after K months.
∴ Investments of A and B are in the ratio of
10000 × 12: 40000 × (12 – K) = 1:1
∴ 10000 × 12 = 40000 × (12 – K)
i.e, 4(12 – K) = 12 ⇒ K = 9.

S5. Ans.(c)
Sol. Let, B’s contribution be Rs. x
∴  (3500×12)/7x = 2/3
or, x=(3500 × 12 × 3)/(7 × 2)
∴x = 9000.

S6. Ans.(c)
Sol. Ratio of their investments
= 70 × 36: 105 × 30: 140 × 24
= 12: 15: 16.

S7. Ans.(a)
Sol. Ratio of their profits
= 75 × 36: 125 × 33: 150 × 27
= 3 × 36: 5 × 33: 6 × 27
= 3 × 12: 5 × 11: 6 × 9
= 36:55:54.

S8. Ans.(a)
Sol. A, B and C pay in the ratio of
10 × 7 : 12 × 5 : 15 × 3
i.e., 70:60:45
i.e., 14:12:9
∴ C pay Rs. (9/35) × 175 = Rs. 45.

S9. Ans.(b)
Sol. Ratio of investment of Arun: Bakul
= 38000 × 12: 55000 × 7 = 38 × 12 : 55 × 7
= 456:385 ≈ 45:38
Required difference = (22000/(45 + 38)) × (45 – 38)
=(22000 × 7)/83 ≈ 22000/12 ≈ 1835 ≈ Rs. 1856.

S10. Ans.(d)
Sol. A’s share for managing the business
= 12 1/2% of Rs. 880 = Rs. 110
Remaining profit = Rs. 770
Profit ratio of A and B = 5:6
A’s share = 5/11 of Rs. 770 = Rs. 350.
A’s total profit = Rs. 350 + Rs. 110 = Rs. 460. Join India's largest learning destination
