Question

Mahesh works for 5 hours and 20 mins a day. For how many minutes will he work in 5 days?

• A. $320\text{mins}$
• B. $1600\text{mins}$
• C. $1400\text{mins}$
• D. $800\text{mins}$

Answer 1

The correct option is B $1600\text{mins}$

$1\text{hour}=60\text{mins}\Rightarrow 5\text{hours}=5\times 60\text{mins}=300\text{mins}\therefore 5\text{hour}20\text{mins}=(300+20)\text{mins}=320\text{mins}$

So, in 5 days, Mahesh will work for $5\times 320\text{mins}=1600\text{mins}.$
