Practicing Success
The second number in the given number pairs is obtained by performing certain mathematical operation(s) on the first number. The same operation(s) are followed in all the number pairs except one. Find that odd number pair. |
43 : 84 21 : 40 15 : 210 19 : 36 |
15 : 210 |
The logic followed here Is : (Ist number)× 2 - 2 = second number 43 : 84 = 43 × 2 - 2 = 84 21 : 40 = 21 × 2 - 2 = 40 15 : 210 = 15 × 2 - 2 = 28 ≠ 210 ODD 19 : 36 = 19 × 2 - 2 = 36 |
