Step-by-step explanation:
she was my first you show me your face now cover photo from thoughts of
Gautham and his wife Gowri will be able to sell 72 apples if they work from 6 am to 6 pm.
Given:
It is given that Gautham and his wife Gowri can pluck an apple in 15 minutes and 12 minutes respectively. And Priya eats an apple in 20 minutes.
To Find:
How many apples Gautham and Gowri will be able to sell in the market if they work from 6 am to 6 pm.
Solution:
The time from 6 am to 6 pm is 12 hours in minutes is 12×60 = 720 minutes.
So, Gautham plucks in 15 minutes and Gowri in 12 minutes.
In 720 minutes Gautham plucks 720/15 = 48 apples.
In 720 minutes Gowri plucks 720/12 = 60 apples
Total apples in 720 minutes = 48+60 = 108 apples.
If Priya eats an apple in 20 minutes, then in 720 minutes, she eats
720/20 = 36 apples she will eat.
So 108 apples - 36 apples
= 72 apples.
∴Gautham and Gowri will be able to sell 72 apples if they work for 720 minutes.
