Answer Key-
Q-(1) Sol-(3)
x + 30% × x = 1.3x
0.3x = 48
x = 160
1.3 × 160 = 208

Q-(2) Sol-(3)
C.P: S.P = 10: 11
C.P: S.P = 9: 10.5
0.5 = 5
1 = 10
10 = 100

Q-(3) Sol-(4)
A = 3960, T = 2 and P = 2640
A = P(1 + r/100)t
3960 = 2640(1 + r/100)2
2640/P = 3960/2640
P = (2640 × 2640)/3960
P = 1760

Q-(4) Sol-(2)
{3/5 × (5 – x)}/{2/5 × (5 – x) + x} = 1/1
3 – 3x/5 = 2 – 2x/5 + x
1 = 6x/5
x = 5/6

Q-(5) Sol-(2)
Maximum number should be negative = 52

Q-(6) Sol-(2)
12.5 × 14 ÷ 8.75 + 42 = 50 + ?
20 + 42 = 50 + ?
? = 62 – 50 = 12

Q-(7) Sol-(5)
150% of 460 + 24% of 650 = ?
690 + 156 = ?
? = 846

Q-(8) Sol-(1)
442 + 232 = (?)2 + 44
1936 + 529 – 256 = (?)2
(?)2 = 2209
? = 47

Q-(9) Sol-(3)
504 ÷ 42 × 7 – 63 + 28 = ?
12 × 7 – 63 + 28 = ?
84 – 63 + 28 = ?
? = 49

Q-(10) Sol-(4)
68 × ?1/2= 591 + 3421
?1/2= 4012 ÷ 68
?1/2= 59
? = 3481
