1) 3
2) 4
3) 1

Answer & Explanation 1. 3 2. 1 3. 5 4. 2 5. 3/4 * 40/360 * 24 = 2 hours
= 110/90 * 100 = 122 2/9
= (85 – 35)/360 * 24 = 3hours 20min
= 40/360 * 100 = 11 1/9%
If the time spends in shcool is equal to that of spent in sleeping, then angle of sleeping is increased by 20degrees. Hence, his time of games is decreased by 20degrees.
= 20/35 * 100 = 57 1/7%
