Answer 1

Answer:

Therefore, the number is 45. ans/-

Step-by-step explanation:

Let the number be x.

Then, ATQ

x + 5 × 5 = 250

5x + 5 = 250

x = 250/5 - 5

x = 50 - 5

x = 45

Verifying the answer, we get

LHS = 45 + 5 × 5

= 50 × 5

= 250

RHS = 250

Therefore, LHS = RHS.

Answer 2

(x +5) x2 =250

5x +10 =250

5x = 250 -- 10

5x =240

x = 240 ÷ 5

= 48 answer
