Sheela can stitch a suit in 2 days, while Meena can stitch a suit in 1 1/2 days. How many days will both take in stitching 35 suits ?
Elementary MathematicsTime and Work
- A32 days
- B33 days
- C30 days
- D40 days
Explanation
Sheela's rate is 1/2 suit per day and Meena's is 1/(3/2) = 2/3 suit per day, for a combined 7/6 suits per day. For 35 suits the time is 35 ÷ (7/6) = 35 × 6/7 = 30 days. This is option (c).
