# Seeta and Geeta go for a swim after a gap of every 2 days

LCM HCF
Seeta and Geeta go for a swim after a gap of every 2 days and every 3 days respectively. If on 1st January both of them went for a swim together, when will they go together next?

- 7th January
- 8th January
- 12th January
- 13th January

### Answer

They will go again together in LCM of (2+1) and (3+1) days

= LCM of 3 and 4 = 12

Hence, 12 days after 1st January = 13th January.

**The correct option is D.**
