Question 1019965
To keep the product of two numbers same if one number is increased by 40% then by what percent the other number is diminished 
:
let p = per cent required in decimal form
let the two number be x & y
:
1.4x * py = x * y
divide both sides the xy
1.4p = 1
p = .7143 * 100 = 71.43% of the 2nd number
:
"by what percent the other number is diminished"
100 - 71.43 = 28.57%
