Neha and Shruti works for 7 days, Neha works for 6 hours in a day and Shruti works for 10 hours in a day. How many hours do both of them work in 7 days?

122 hours

Step-by-step explanation:

Since Neha works for 6 hours a day, you multiply that number by the amount of days she works (so basically just do 7 x 6 and that'll equal 42). Neha works for 42 hours and seven days. Now take the amount of hours Shruti works for and multiply it by Seven (the amount of days they work), so you do 10x7, which is 70.

Add the total hours of 70 (Neha's hours) and 42 (Shruti's hours) and the answer is 112 hours.
