Select the option that is related to the fifth number in the same way as the second number is related to the first number and the fourth number is related to the third number.
15 : 223 :: 8 : 62 :: 13 : ?
15² - 2 = 225 - 2 = 223 8² - 2 = 64 - 2 = 62 Similarly, 13² - 2 = 169 - 2 = 167
375% of 320 - 80% of 40 ÷ √256 = ?
√? = 80% of 720 - 22% of 2500
9999² + 1111² =?
What is the value of 143 + 163 + 183 + … + 303?
45% of 360 - 160 + ? = √324
Find the value of {(3125) (n/5) × 5 (2n + 2) }/ {25 n × 5 (n - 1) }
263 + 1152 - ? + 577 = 1333
? + 156 ÷ 3 × 7 = 35% of 400 + (13)2
(72 + 30) ÷ 6 + [{75 ÷ 25) + 6} × 2] = ?
34 × 2.5 + 6.4 × 1.5 – 4.8 × 1.2 =?
