Question

54 is divide into two parts such the 10 times the First part and 22 times the part is 780 what is the bigger part​

Answer 1

Answer:

Step-by-step explanation:

let us divide 54 into 2 parts, say x and (54- x).

So 10 x + 22 (54-x) = 780 (given)

10 x + 22x54- 22x = 780

10 x +1188 - 22 x =780

10 x - 22x = 780 -1188

On simplification 12 x = 408

So x = 34 and 54-x = 54 - 34 = 20

So the 2 parts are 34 and 20.

The larger part is 34.

Answer 2

Let the two parts be (54 - x) and x.

Then, 10 (54 - x) + 22x = 780

=> 12x = 240  

=>  x = 20.

Bigger part = (54 - x)  = 34.
