Question
Bheem can eat few laddus in 20 days and kalia can eat same number of laddus in 30 days. In how many days can Bheem and Kalia together eat the laddus?
Solution
Let's solve this step by step:
Step 1: Let's assume the total number of laddus is L.
Step 2: Bheem can eat L laddus in 20 days, so Bheem's rate of eating laddus is L/20 laddus per day.
Step 3: Kalia can eat L laddus in 30 days, so Kalia's rate of eating laddus is L/30 laddus per day.
Step 4: When Bheem and Kalia eat together, their combined rate is the sum of their individual rates. So, their combined rate is (L/20 + L/30) laddus per day.
Step 5: Simplifying the above expression, we get their combined rate as (3L/60 + 2L/60) = 5L/60 = L/12 laddus per day.
Step 6: Therefore, Bheem and Kalia together can eat L laddus in 12 days.
