Answer 2

The second should be diminished by 28.57%.

Step-by-step explanation:

Let the one number is x and another number is y.

The product of two numbers remains constant.

xy =  k          Where k = constant

If one number increases by 40% = $\frac{140}{100}x = 1.4x$

So, 1.4xy = 1.4k

=> 1.4xy x $\frac{1}{1.4}$  = k

$\frac{1}{1.4}$ = 0.7142857 = 71.43 %

y should be diminished by 100 - 71.43 = 28.57%

Hence, the second should be diminished by 28.57%.
