Option 3 : 700

Let the number be 100%.

⇒ 1/4 = 25%,

According to the question,

⇒ 25% - 20% ≡ 35

⇒ 5% ≡ 35

⇒ 1% ≡ 7

⇒ 100% ≡ 700

∴ The number is 700.

**Traditional method:**

**Calculation:**

Let the number be x.

According to the question,

⇒ x × (1/4) = 20% of x + 35

⇒ x/4 = x/5 + 35

⇒ x/4 - x/5 = 35

⇒ (5x - 4x)/20 = 35

⇒ x/20 = 35

⇒ x = 700

**∴ The number is 700.**
