Seventy eight is divided into two parts such that four times the first part and five times the second part are in the ratio 14 : 15. The first part is: |
42 36 30 48 |
42 |
Here, x + y = 78, \(\frac{4x}{5y}\) = \(\frac{14}{15}\) ⇒ x : y = 14 : 12 = 7 : 6 ⇒(7 + 6) units = 78, ⇒ 13 units = 78 ⇒ 1 unit = 6 ⇒ x = 7 x 6 = 42. |
