solution
Directions (Q. 1-5): What value should come in the place of question mark (?) in the
following equations?
1). 213×68 = 246228 ÷ ?
a) 16
b) 17
c) 18
d) 19
e) 21
2). (19)7.3 ×
(1/6859) ÷ (361) -2.1 = (√19)?
a) 7.5
b) 15
c) 8.5
d) 17
e) 9.5
3). 3√[(46600)+√ 3136] + 3√[(29750)
+ √ 1681]= ?
a) 61
b) 63
c) 65
d) 67
e) 69
4). 2197/? = ?/1872
a) 2028
b) 2132
c) 2248
d) 2372
e) 2496
5). 7.4 % of 3455 + 6.25 % of 293.28 = ?
a) 248
b) 256
c) 268
d) 274
e) 286solution
1). B)
2). D) (19)7.3 ×
(19)-3 ÷ (19) -4.2 = (19)7.3 - 3 + 4.2 = (19)8.5 = (√19)17
3). D) 3√(46600 + 56) + 3√(29750 + 41) = 3√46656 + 3√29791
= 36 + 31 = 67
4). A) (?)2 =
2197×1872 = 169×13×13×144 = (13×13×12)2
? = 13×13×12 = 2028
5). D) ? = (7.4×34.55) + (6.25×2.9328) = 255.67 + 18.33 = 274
