Question

A sum of RS 140 is divided into two parts. If two times the greater part is 15 less than three times the smaller part . Find the parts of the sum​

Answer 1

greater part = Rs.81

smaller part = Rs.59

Explanation:

Solution:

Let the greater part be x and smaller part be (140 - x)

Acccording to question,

or, 2x+15 = 3(140 - x)

or, 2x+15 = 420-3x

or, 2x+3x = 420-15

or, 5x = 405

or, x = 405÷5

x = 81

Therefore, the greater part = x = 81

the smaller part = (140-x) =(140-81) = 59
