Answer Key-
Q-(1) Sol-(1)

(4.5)^{3.7+ 2 × 1.3 + 3 × 1.8} = 4.5^{?+ 5.2}
? = 3.7 + 2.6 + 5.4 - 5.2,  ? = 6.5

Q-(2) Sol-(2)

14449 + 40 × 35 - 40 = ?, ? = 12809

Q-(3) Sol-(1)

?=6

Q-(4) Sol-(5)

?= –160

Q-(5) Sol-(5)

142% of 240 – 142% of 240=?

?=2% of 240=4.8

Q-(6) Sol-(4)

3x-10 = 2x-5
x = 5
Suml = 15 + 20 = 35 years

Q-(7) Sol-(1)

A+B+C = 300 (i)
A + C = 188  (ii)
B + C = 152  (iii)
from (i), (ii) and (iii)
C = Rs. 40

Q-(8) Sol-(2)

Req. consumption  = 30 × 3 × 3
 = 270 Kg.

Q-(9) Sol-(2)

Ratio = Anu : Vijay : Charu
4 : 3
2 : 3
= 8 : 6 : 9
Charu's share = 9/23×46000
 = Rs. 18000

Q-(10) Sol-(4)

2(M+N+O)’s 1 day work = (1/30+1/24+1/20)=1/8

=>(M+N+O)’s 1 day’s work= 1/16

work done by M, N and O in 10 days= 10/16=5/8

Remaining work= (1 – 5/8)

M’s 1 day’s work = (1/16 – 1/24)=1/48

Now, 1/48 work is done by M in 1 day.

So, 3/8 work wil be done by M in 48×3/8 = 18 days
