Answer Key-

Q-(1) Sol-(1)
× 1.5 + 0.5, × 2 + 1, × 2.5 + 1.5, × 3 + 2, × 3.5 + 2.5

Q-(2) Sol-(3)
+ 13, + 23, + 33, + 43, + 53

Q-(3) Sol-(2)
27 + 56 = 83
56 + 83 = 139
83 + 139 = 222
139 + 222 = 361

Q-(4) Sol-(5)
× 1 – 1, × 2 – 4, × 4 – 16, × 8 – 64, × 16 – 256

Q-(5) Sol-(4)
÷ 2, × 3, ÷ 2, × 3, ÷ 2

Q-(6) Sol-(2)
(2365 ÷ 47.3)% of 6872 + ?% of 480 = 5836
50% of 6872 + ?% of 480 = 5836
3436 + ?% of 480 = 5836
?% of 480 = 5836 – 3436 = 2400
? = (2400 × 100) ÷ 480 = 500

Q-(7) Sol-(5)
(?)2 – 325 × 9.8 = 1.4 × 625 + 4.2 ÷ 0.7 + 159
(?)2 = 875 + 6 + 159 + 3185
(?)2 = 4225
? = 65

Q-(8) Sol-(3)

Required answer=7500

Q-(9) Sol-(4)
Sum of 20 observations = 1600
Sum of 18 observations = 78 × 18 = 1404
Sum of two (Smallest + Largest) = 1600 – 1404 = 196
Difference of two (Largest – Smallest) = 132
Largest number = 328/2 = 164

Q-(10) Sol-(2)
23 + 12 = 105
35 = 105
1 = 3
Required cost = Rs. (69 × 36 × 4.50) = Rs. 11178
