**ANSWERS WITH EXPLANATIONS**

1.(d)
Total decrease = 20 * 2 = 40 month

=
3 years 4 month

So,
age of new boy = 18 years – 3 years 4
month

=
14 years 8 month

2.Sum
= (100× S.I.)/ r × t

=
(100 × 4016.25)/ 9 × 5 = Rs. 8925

3.S.I.
for 3 years = Rs. (12005 - 9800) = Rs. 2205.

S.I.
for 5 years= Rs. 3675

Principal
= Rs. (9800 - 3675) = Rs. 6125

Hence
Rate = {(100 × 3675) / 6125 × 5} % = 12 %

4..
Lcm of 5&6 =30

Cost
price of 30 articles= 5/6*30 = 25

Selling
Price of 30 articles = 6/5*30 =36

%
profit = (36-25)/25*100= 44%

5.
Selling Price With Profit of 10 % of
total cost = 3000*10*110/100= 33000

Selling
Price of 2 cows with 5% loss= 6000*95/100= 5700

Difference
= 33000-5700= 27300;

So
rate of the cows for selling to gain 10% profit on total = 27300/7= Rs. 3900

(because
1 cow died so remaining= 10-1-2=7)

6.
In first case, We take 1. 20, 1.44 & 1. 41

In second case, We take 1.20,
1. 74 & 1. 41

so,

11 : 7

Since I :
II
= 1.7

I :
III
= 11 : 7

So,
I : II : III
= 11 : 77 : 7

7.B

Ratio
capital of Anil, mukesh and Ritesh.

=
( 20,000 x 4 + 14000 x 8 ) : ( 20,000 x 4 + 12000 x 8 ) : ( 20,000 x 4 + 26000
x 8 )

=
192000 : 176000 : 288000

Anil
share = (65600 x 192 / 656 ) = 19200

Mukesh
share = ( 65600 x 176 / 656 ) = 17600

Ritesh
share = (65600 x 288 / 656 ) = 28800

8. A
Step 1: we can assume that amar join into business after x months.So
amar money was invest into (12 – x ) months.

Step
2: 76000 x 12 / 57000 x ( 12 – x ) = 2 / 1

912000
= 114000 ( 12 – x ) = 114 ( 12 – x ) = 912 = x = 4

After
4 months amar join the business.

9
.B

Probability
of choosing u - 2/8 = 1/4

10.D

No.
of ways = {8! /(2! * 2!)}×{4!/2!}= 10080 *12 =120960
