Ans: 4
?x8 = 293 – 22×750/100 = 293 – 165 = 128
=> ? = 16

421
None of these

Ans: 1
0.35 x 34 x 55 + 456.6 = 699.1 + ?
=> ? = 654.5 + 456.6 – 699.1 = 412

? = 32.5 x 0.26 x 150 – 745.5 = 1267.5 – 745.5 = 522

5. Question

22.5% of 1400 + 12.5% of 2560 = 144% of 750 – ?

Ans: 4
22.5 x 14 + 12.5 x 25.6 = 144 x 7.5 – ?

=> ? = 1080 – 315 – 320 = 445

Directions:(6-10) What should come in place of the question mark(?) ?

None of these

Ans: 1
6^1.2 x 6^2x x 5^2.6 = 30^2.6 = 6^2.6 x 5^2.6Hence, 1.2 + 2x = 2.6
Or x = 0.7
