Explanation with Answers

1). D) √(15+24x0.5) / √(10.2 ÷ ?) = 3
or, √27/3 = √(10.2 ÷ ?)
or,√3  = √(10.2 ÷ ?)
Squaring both sides, we get
3 = 10.2 ÷ ?
? = 10.2 / 3= 3.4

2). B) ? ÷ 25
= √[(2) + (1/144)] ÷ √[(1) + (49/576)] × (27/34)
=  √(289/144) × √(576/625) = (17/12) × (24/25) × (27/34) = 27/25
? = (27/25) × 25 = 27

3). E)  65 x 9 ÷ ? = 101 + √256 = 101 + 16 = 117
or, ? = (65x9) /117 = 5

4).  A) 5/3 of 1440 + 40% of 3550 - ? = 612
or, 5/3 x 1440 + 2/5 x 3550 - 612 = ?
or, 5 x 480 + 2 x 710 - 3721 = ?
or, ? = 2400 + 1420 - 3721 = 99

5). B) ? ÷ (25% of 289 – 32  3/4 ) = 0.2 
or, ? ÷ [(1/4) × 289 – (131/4)] = 0.2
or, ? ÷ (289-131)/4 = 0.2
 or, ? x (4/158)= 0.2
? = (0.2 x158)/4 = 0.2 x 39.5 = 7.9

6). C) 84 + 142 = ? x 105 ÷ 8.25
or, 84 + 196 = (? x 105) / 8.25
? = (280x8.25)/105 = [(280x8) + 280x(1/4)] / 105
= (2240+70) /105 = 2310/105 = 22

7). B) (12.5 x 14) ÷ 20 + 41.25 = (?)÷ 2.5
or, 8.75+41.25 = ?3 / 2.5
or, 50 × 2.5 = ?3
? = 3√(5×5×5) = 5

8). B)  0.36 × 0.36 + 0.28 x 0.36 + 0.142
(a + b)= a2+ 2ab + b2
So, (0.36 + 0.14)2 =- (0.5)2 = 0.25

9). A) [465/15 -25] =2x
           465/15=25+2x
            31=25+2x
             2x=6
                x=3


10). A          958 +150x/100=2500
                       150x/100=1542
                        x=154200/150
                         x=1028
