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 = ?

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 = ?

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

##### 6. Question

160.02 x 14.97 = ? – 280.01 x 3.02

Ans: 2
? ≈ 160 x 15 + 280 x 3

= 2400 + 840 = 3240

##### 7. Question

29.012 – 1088.98½ + 1000.01 = ?

Ans: 2
292 = 841, 332 = 1089, 103 = 1000
? ≈ 841 – 33 + 10
= 818
