Question

13,680 made of three parts, of which the first 3 parts, the third part and the second and third parts have a ratio of 4: 7.​

Answer 1

Step-by-step explanation:

as we don't know the first number ratio

we will mark it as x , 4x,7x

so :-

x+4x+7x = 13,680

12x = 13,680

x = 13,680/12

x = 1,140

now the actual value of numbers

1) x = 1,140

2)4x = 4,560

3) 7x = 7,980
