Question

• A number is divided in the ratio 15 : 8. If the second part is 56, find the number​

Answer 1

Answer:

80 and 100

Step-by-step explanation:

1] The ratio of numbers is 4:5

Let the common factor be x .

Thus , 4x+5x = 180 ....(from given condition)

Hence , 9x=180

x=20

Thus , numbers are 4x = 4×20 = 80 and 5x=5×20=100

∴The numbers are 80 and 100

2] Let the common ratio be x.

∴8x = 56

∴x=7

∴15x=15×7=105

∴ The original number is 105+56 = 161
