(?24 + ?216) / ?96
= (?4 x 6 + ?36 x 6 ) / ?16 x 6
= 2?6 + 6?6
= 8?6 / 4?6
= 2
Correct Answer: 0.94
Explanation:
?0.9 = ?0.90
= ?90/100
= ?90/10
= 9.4/10
= 0.94
Correct Answer: 0.3

Given expression = ?0.01 + 0.08
=?0.09
= 0.3
Correct Answer: 0.3
Explanation:
Given expression = ?0.0009 / ?0.01
= ?0.0009 / 0.0100
= ?9 / 100
= ?9 / ?100
= 3 / 10
= 0.3
Correct Answer: .0243
Explanation:
?.00059049 = ?59049/100000000
= ?59049 / 10000
= 243/10000
= 0.0243
Correct Answer: 0.63

Exp. = ?0.16 / 0.40
= ?16 / 40
= ?4 / 10
= ?0.4
= ?0.40
= ?40 / 100
= ?40 / 10
= 6.3 / 10
= 0.63
Correct Answer: 0.252
Explanation:
?0.064 = ?0.0640
= ?640/10000
= ?640 / 100

= .03
Correct Answer: 42
Explanation:
74088 = 2 x 2 x 2 x 3 x 3 x 3 x 7 x 7 x 7
= (2x2) x (3x3) x (7x7) x (2x3x7)
Least number which should be multiplied to 74088 to make it a Perfect square = 2 x 3 x 7 = 42
