Question

two numbers are such that the ratio is 4:7.If each is increased by 4 ,the ratio becomes 3:5. The lager number​

Answer 1

Step-by-step explanation:

let the no. be x

since the two no= 4x and 7x

a/q

• 4x + 4/ 7 x +4 = 3/5
• 5 ( 4x +4) = 3 ( 7x + 4)
• 20x +20 = 21x + 12
• 20x - 21x = 12 - 20
• -x = -8
• x = 8

So , the two no.

4x = 4× 8

= 32

and

7x = 7× 8

= 56

Hence , the larger no. is 56.
