Question

Tom studies for $5\frac{1}{4}$ hours daily. He devotes $2\frac{3}{4}$ hours of his time for English and Mathematics. How much time does he devote for other subjects?

• A. $2\frac{1}{2}$ hrs
• B. $8$ hrs
• C. $\frac{1}{2}$hrs
• D. $1$ hr

Answer 1

The correct option is A $2\frac{1}{2}$ hrs

Total time taken by Tom to study all the subjects $=5\frac{1}{4}=\frac{21}{4}$

Time taken to study English and Mathematics = $2\frac{3}{4}=\frac{11}{4}$

Time for other subjects = $\frac{21}{4}-\frac{11}{4}=\frac{10}{4}=\frac{5}{2}=2\frac{1}{2}$ hrs
