Question

Raj studies for 3.2 hours every day and he studied for two and a half weeks. How many hours did he study in total?

• A. 55
• B. 54
• C. 56
• D. 8

Answer 1

The correct option is C

56

Given:
Number of hours studied in a day =$3.2hours$
Number of weeks he studied=2$\frac{1}{2}weeks$
Number of days in 2$\frac{1}{2}$ weeks =$7+7+\frac{1\times 7}{2}week$ =$17.5days$

$\therefore$ total number of hours studied= $3.2\times 17.5$ = $56hours$

Hence, he studied for 56 hours in a week.
