Question

four fifths of a number is 10 more than two thirds of the number. Find the number​

Answer 1

Answer:

Let the number required is x

According to the question we can write as

(4/5)x−10=(2/3)x

On rearranging,](4/5)x−(2/3)x=10

Now taking the L.C.M of 3 and 5 is 15

(12x−10x)/15=10

On cross multiplication,

2x=150

x=150/2=75

So the required number is 75

Answer 2

Step-by-step explanation:

let the number = x

2x/3+10=4x/5

10 =4x/5 - 2x/3

10 =12x/15 - 10x/15

10 =2x/15

10*15 =2x

150/2=x

75 = x

x = 75
