प्रश्न
Five times the price of a pen is Rs 17 more than three times its price. Find the price of the pen.
उत्तर
Let the price of one pen be Rs x.
According to the question:
5x = 3x + 17
or, 5x − 3x = 17 [Transposing 3x to the L.H.S.]
or, 2x = 17
or, `(2x)/2=17/2` [Dividing both the sides by 2]
or, x = 8.50
∴ Price of one pen = Rs 8.50
