1. A 70cm long wire is to be cut into two pieces such that one piece will be 2/5 as long as the other. How many centimetres will the shorter piece be ?
- A. 10
- B. 10
- C. 10
- D. 10
Answer: Option C
Explanation:
Hints: Let the other price be of length x cm, so the shorter price = 2/5 of x = 2x / 5
Now, 2/5 x + x = 70
7/5 x = 70
x = 50 and 2/5 x = 2/5 × 50 = 20 cm
