Question 141

The difference between 42% of a number and 28% of the same number is 210.what is the 59% of that number

Solution

Let the number = $$100x$$

Acc. to ques,

=> $$(\frac{42}{100} \times 100x) - (\frac{28}{100} \times 100x) = 210$$

=> $$42x - 28x = 14x = 210$$

=> $$x = \frac{210}{14} = 15$$

=> Number = $$100 \times 15 = 1500$$

$$\therefore$$ 59 % of the number = $$\frac{59}{100} \times 1500$$

= 885
