The correct answer is A 882.
According to the question, we are looking for an approximate number, not the exact value of 140% of 630.
The number we are looking for is greater than 100% (140% to be exact) of the original number, so we are looking for numbers that are bigger than the original. This allows us to automatically eliminate 74 as the answer.
In order to work out the answer we have to multiply 630 by 1.4
or alternatively, multiply 0.4*630= 252
and add 630
252 + 630 = 882
The correct answer is 882.
