? = 31% of 1508 + 26% of 2018
= 1508 x 31 + 20.18 x 26Correct Option: C
? = 31% of 1508 + 26% of 2018
= 1508 x 31 + 20.18 x 26
= 467.48 + 524.68
≈ 992.16 = 1000

? = 22.5% of 1350 + 135 % of 225
= (1350 x 225)/100 + (225 x 135)/100Correct Option: B
? = 22.5% of 1350 + 135 % of 225
= (1350 x 225)/100 + (225 x 135)/100
= 303.75 + 303.75 = 607.5 ≈ 610

? = 35% of 121 + 85% of 230 .25
= (121 x 135)/100 + (230 x 85)/100Correct Option: C
? = 35% of 121 + 85% of 230 .25
= (121 x 135)/100 + (230 x 85)/100
= 4235 + 195.55 = 237.85 ≈ 240

134% of 3894 + 38.94% of 134 = ?
⇒ ? = (3894 x 134)/100 + (38.94 x 134)/100
= 5217.96 + 52.1796Correct Option: D
134% of 3894 + 38.94% of 134 = ?
⇒ ? = (3894 x 134)/100 + (38.94 x 134)/100
= 5217.96 + 52.1796
= 5270.1396 ≈ 5270

√625.04 x 16.96 +136.001 ÷ 17 = ?
∴ ? = √625 x 17 + 136 ÷ 17Correct Option: D
√625.04 x 16.96 +136.001 ÷ 17 = ?
∴ ? = √625 x 17 + 136 ÷ 17
= 25 x 17 + 136 ÷ 17
= 425 + 8 = 433
