UPSC CDS 1 2022 Math Paper

Concept Used:
1 Week =7 Days
1 Day =24 Hours
1 Hour =60 Minutes
Calculation:
We have to find total minutes in x weeks and x days
x weeks x days =(x×7) days +x days
⇒8x days =8x×24 hours
⇒192x hours =192x×60 minutes
⇒11520x minutes
∴ The total minutes in x weeks and x days is 11520x minutes.
