**Next topic is Simple interest and Compound interest.**

**Answers:**

**1.(B)**

Let initial investment of A is 3x and B is 5x, then C investment is also 5x, but most important to note in this question is the time duration of investment

Like, A invested for 12 months, B invested for 12 months and C invested for 6 months.

A:B:C =(3x*12):(5x*12):(5x*6)

= 36:60:30

= 6:10:5

**2.(B)**

Let their investments be Rs. x for 14 months, Rs. y for 8 months and Rs. z for 7 months respectively

Then, 14x : 8y : 7z = 5 : 7 : 8

Now, 14x/8y = 5/7

y = (49/20)x

14x/7z = 5/8

z = (16/5)x

x:y:z = x:(49/20)x:(16/5)x

20:49:64

**3.(A)**

Let B contribution is x.

(3500∗12)/7x=2/3

14x=126000

x=Rs9000

**4.(B)**

Share of one grandchild=1/10*1.25=Rs.0.125 lakh

Each son gets=8*0.125=Rs.1 lakh

Share of 3 sonns=Rs.3 lakhs

Share of 2 daughters=2*1.25=Rs.2.5 lakhs

Total shares of sons and daughters=Rs.5.5 lakhs

Wife's share=2/5*5.5=Rs.2.2 lakhs

Share of three grandchildren=3*0.125=Rs.0.375 lakhh

Required answer

=(2.2+0.375)lakh

Rs.2.575 lakhs

Rs.257500

**5.(B)**

Suppose Ramesh invested Rs. x. Then,

Manoj : Ramesh = 120000 * 6 : x *12.

720000/12x : 6000/3000

x = 30000

**6.(D)**

Just take care of the months of investment, rest all will be simple.

Yogesh:Pranab:Atul = 45000*12:60000*9:90000*3

= 2:2:1

Atul's share = Rs. 20000 * (1/5) = Rs. 4000

**7.(D)**

A:B = 3:2 = 6:4

A:C = 2:1 = 6:3

A:B:C = 6:4:3

B share = (4/13)*157300

= 48400

**8.(C)**

A:B: C = 16000*3 + 11000*9:12000*3 + 17000*9:21000*6

= 147:189:126 = 7:9:6

Difference of B and C's shares =

Rs. [26400 * (9/22)-26400 * (6/22))

= Rs. 3600

**9.(B)**

For managing, A received = 5% of Rs. 7400 = Rs. 370.

Balance = Rs. (7400 - 370) = Rs. 7030.

Ratio of their investments = (6500 x 6) : (8400 x 5) : (10000 x 3)

= 39000 : 42000 : 30000

= 13 : 14 : 10

B's share = Rs.(7030 x14/37)= Rs. 2660.

**10.(B)**

Aman : Rakhi : Sagar = (70,000 x 36) : (1,05,000 x 30) : (1,40,000 x 24) = 12 : 15 : 16.
