1. A 40-meter long rope is cut into two unequal pieces. If one piece is 18 meter longer than the other, what is the length ( in meter ) of the shorter piece ?
- A. 10
- B. 10
- C. 10
- D. 10
Answer: Option B
Explanation:
Let,
shorter length = X
∴ Bigger length = X + 18
ATQ,
X + (X + 18) = 40
2x + 18 = 40
2x = 40 - 18
2x = 22
∴ x = 11
