Question

Urmila wears sarees every 2 days.She wears her designer jewellery every 3 days.If she wears saree with designer jewellery on December 1st ,What are the next three days she will wear both saree and designer jewellery ?

Answer 1

If Urmila wears saree every 2 days and wears jewellery every 3 days, then to calculate the days she wears both of them together , we will have to take the LCM i.e. LOWEST COMMON MULTIPLE of the two numbers.
lcm of 2 and 3 is 6 
so, she will wear both of them every 6 days.
so, after december 1 it will be december 7, then december 13 and then december 19.
