What will come in place of question mark ‘?’ in the following questions?
47.9856 * 47.0144 - 47 = ?
Verify mobile number to view the solution
The formula used is xa * xb = xa+b
234 ∗ 9/39 + 14 = ?
234 = 39 * 6 So, the expression is 39*6*9/39 + 14 = 54 + 14 = 68
88 ∗ 6.4 ∗ 0.7 = ?
88 * 6.4 = 563.2 563.2 * 0.7 = 394.24
8.13 + 98.01 + 764.87 + 1234.56 = ?
1234.56 + 764.87 = 1999.43 1999.43 + 98.01 = 2097.44 2097.44 + 8.13 = 2105.57
87501 + 265791 − 18765 = ?
87501 + 265791 = 353292 353292 - 18765 = 334527
The quotient of 8746 ÷ 6 + the quotient of 16740 ÷ 4 = ?
8746 / 6 = 1457.67 So, the quotient is 1457 16740 / 4 = 4185 So, the answer is 1457 + 4185 = 5642
1502 = 22500 1602 = 25600 So, the answer should be between 150 and 160. From the options, checking for 154, we see that it satisfies. Option b) is the correct answer.
18 ∗ 16 ∗ 48 ∗ ? = 1658880
18*16 = 288 288*48 = 13824 1658880/13824 = 120
912 + 632 − 152 = ?
912 = 8281 632 = 3969 152 = 225
The expression boils down to 8281 + 3969 - 225 = 12025
(450 ÷ 22.5) × (320 − ?) = 60
By BEDMAS rule, brackets are solved first. So, 450 ÷ 22.5 = 20 20 x (320 - ?) = 60 320 - ? = 3 So, ? = 320 - 3 = 317
