Correct Answer: 7
Explanation:
3 7.5 ÷ 271.5 x 92 = 3?
? 37.5 ÷ (3)3 x 15 x 32 x 2 = 3 ?
? 37.5 - 4.5 + 4 = 3? ? 37 = 3? ? ? = 7
Correct Answer: 2.7

? = 953.7 ÷ 950.9989 = 95?
? 95(3.7 - 0.9989) = 95?
? 952.7011 = 95?
? ? = 2.7011 ? 2.7
Correct Answer: 2
Explanation:
[137 ÷ 17 x 3.99]/[4.02 x 3.98] = ? ? (137 ÷ 17 x 4) / (4 x 4) ? 2
Correct Answer: 10000
Explanation:
99.999 ÷ 0.99 ÷ 0.00991234
= 100 ÷ 1 ÷ 0.01 = 10000
Correct Answer: 20
Explanation:
(9.95)2 x (2.01)3 = 2 x (?)2
Here, 9.95 is Approximated to 10, 2.01 is approximate to 2 because calculating the square or cubes of whole number is much easier than to calculate the square or cube of decimal numbers
2 x (?) 2 = ( 10)2 x (2)3 = 100 x 8 = 800
? (?)2 = 400
? ? =20
Correct Answer: 5
Explanation:
?% of 218 = 31/3 x 3.3121
⇒ 218 x ?/100 = 10/3 x 3.3121
∴ ? = 10/3 x 3.3121 x 100/218
= 5.064 = 5
Correct Answer: 6000
Explanation:
? = 161% of 3578 + 139.85 + 5/8 of 161.56
= 5760.58 + 139 .85 + 100.975
6001.405 ? 6000
Correct Answer: 325
Explanation:
36.0001 ÷ 5.998 x ?? = 108.0005
? 36 ÷ 6 x ?? = 108
? 6 x ?? = 108
? ?? = 18
? = 324 ? 325
Correct Answer: 10000
Explanation:
1169.9997 ÷ 18.0011 + 7.0009 x 4.9898 = ??
? ?? ? 1170 ÷ 18 + 7 x 5 = 65 + 35 = 100
? ? = 10000
Correct Answer: 625
Explanation:
1178.999 x 25.0001 - ?? x 16.0011 = 29075
? 1179 x 25 - ?? x 16 = 29075
? 29475 - ?? x 16 = 29075
? ?? x 16 = 29475 - 29075 = 400
? ?? = 25
? ? = 25 x 25 = 625
