प्रश्न
Find two numbers such that one of them is five times the other and their difference is 132.
उत्तर
Let one of the numbers be x.
∴ Second number = 5x
According to the question:
5x − x = 132
or, 4x = 132
or, `(4x)/4=132/4` [Dividing both the sides by 4]
or, x = 33
Thus, the required numbers are x = 33 and 5x = 5 × 33 = 165.
