Question

the number that is to be added to 10% of 320 to get the sum as 30% of 230is​

Answer 1

Answer:

Step-by-step explanation:

Let the number be x.

x is to be added to 10% of 320 = x + 10/100 × 320 = x + 32

x is to be added to 10% of 320 to get the sum as 30% of 230

⇒x + 32 = 30/100 × 230

⇒ x + 32 = 3 × 23

⇒ x + 32 = 69

⇒ x = 69 - 32

⇒ x = 37

∴ The number = x = 37
