Two numbers are less than a third number by 40% and 47% respectively. How much per cent is the second number less than the first ?
Answer/Solution
88%
Steps/Work
Here, x = 40 and y = 47
Therefore second number
= [[(100 - y)/(100 - x )] x 100 ]% of first number
= [[(100 - 47)/(100 - 40 )] x 100 ]% of first number
i.e, 88.3% of the first.
ANSWER:B
Therefore second number
= [[(100 - y)/(100 - x )] x 100 ]% of first number

i.e, 88.3% of the first.
