Correct Answer: 0.024
Explanation:
Sum of decimal places being equal in Num. and Denom. of given expression
So ,Given expression is equivalent to
?(324 x 81 x 4624) / (15625 x 289 x 729 x 64)
= (18 x 9 x 68) / (125 x 17 x 27 x 8)
= 3/125
= 0.024
Correct Answer: 192
Explanation:
?324/ 1.5 = N / ?256
? 18/1.5 = N/16
? N = (18 x 16) / 1.5 = (18 x 16 x 10) / 15
= 192
Correct Answer: 64
Explanation:
Let 1872/?N = 234.
Then ?N = 1872/234 = 8
? N = 8 x 8 = 64
Correct Answer: 49
Explanation:
Let ?25/15625 = ?x/30625
Then, 25/15625 = x/30625
? 1 / 625 = x / 30625
? x = (30625 / 625) = 49
Correct Answer: 170/11
Explanation:
?.289/.00121 = ?.28900/.00121
= ?28900/121
= 170/11
Correct Answer: 9
Explanation:
Let , ?1296 / N = N / 2.25
Then, 36/N = N /2.25 or N2= 36 x 225/100
? N = ?(36 x 225) /100 = (6 x 15) / 10 = 9
Correct Answer: .0243
Explanation:
?.00059049 = ?59049/100000000
= ?59049 / 10000
= 243/10000
= 0.0243
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: 0.3
Explanation:
Given expression = ?0.01 + 0.08
=?0.09
= 0.3
Correct Answer: 0.94
