Select the option that is related to the third number in the same way as the second number is related to first number and the sixth number is related to the fifth number.
7 : 48 :: 12 :: ?
7 ⇒ 7 × 7 = 49 – 1 = 48 Similarly, 12 ⇒ 12 × 12 = 144 – 1 = 143 Hence, option A is correct.
36 x 3.6 ÷ 0.5 ÷ ? = 64
0.25% of 22200 – 18.3 = ?
7(1/2) – 3(5/6) = ? − 2(7/12)
(292 – 141) ÷ 5 + (40 ÷ 2) + 23 = ?
1220 ÷ 61 ÷ 5 + 450 of 20% - 70 = √ ?
(3/7 )Of 3360 ÷ 240 + 30 = (?)²
18 × √225 + 378 ÷ √441 = ? × 9
(3333 ÷30) + (785 ÷25) + (2981 ÷11) = ?
If x + y + 3 = 0, then find the value of x3 + y3 – 9xy + 9.
