Directions:(1-10) What value should come in place of the questions mark (?) in the following questions?

1. Question

23 X √7225 – √3025 x 29 = ?

Ans: 3
23 x 85 – 55 x 29 = ?
=> ? = 1955 – 1595 = 360

2. Question

14² + 9³ + 15² + 11³ = ?

2506
2135
2673
2481
2458

Ans: 4
? = 196 + 729 + 225 + 1331 = 2481

3. Question

?% of 625 + 34% of 450 + 19 x 13 = 750

Ans: 1
?% x 625 + 34 x 4.5 + 19 x 13 = 750
=> ?% x 625 + 153 + 247 = 750
=> ?% x 625 = 350
=> ? = 350/625 x 100 = 56

4. Question

28.5% of 1200 + 21.5% of 1400 + 26% of 2200 – 44% of 1800 = ?

Ans: 3
? = 28.5×12 + 21.5×14 + 26×12 – 44×18
= 342 + 301 + 572 – 792
= 423

5. Question

397 x 397 + 104 x 104 + 2 x 397 x 104 = ?

250001
251001

261001
None of these

Ans: 2
(397)² + (104)² + 2 x 397 x 104
= (397 +104)²(∵ a² + b² + 2ab = (a + b)²) = (501)²= 251001
