Instead of 10%, if the students spends 15% to study other subjects and the time is taken from the time scheduled to study mathematics and if he/she used to study 20 hours per day, then their difference of time for study mathematics per day is:

A) 30 minutes B) 45 minutes C) 1 hour D) 1 hour 30 minutes

Discuss

Answer & Solution

Extra time taken = 15% - 10% = 5%
then difference in mathematics = 5%
∵ 100% = 20 hours
∴ 5% = 1 hours

The time spent to study history and chemistry is 4 hours 30 minutes, Then the student studies physics for:

A) 1 hours 30 min B) 2.9 hour (approx.) C) 2 hours D) 3 hours

Discuss

Answer & Solution

$$\eqalign{ & \text{Time spend in H + C} \cr & = \left(15 + 15 \right)\% \cr & = 30\% \cr & \text{Time spend in P = 20%} \cr & \because 30\% = 4\frac{1}{2} \text{H} = \frac{9}{2}\text{H} \cr & 1\% = \frac{9}{2} \times 30\text{H} \cr & \text{So, } 20\% = \frac{9}{2} \times \frac{20}{30}\text{H} = 3\text{ Hours} \cr & \text{So } 20\% = \frac{3}{20} \times 20 = 3\text{ Hours} \cr} $$

If the student studies 10 hours in a day, then he/she studies mathematic for:

A) 3 hour B) $$\frac{10}{3}$$ hour C) $$\frac{1}{3}$$ hour D) $$\frac{3}{10}$$ hour

Discuss

Answer & Solution

Time spend in mathematics = 30%
∵ 100% = 10 hours
∴ 30% = 3 hours

If then student studies chemistry for 3 hours, then he/she studies geography for:

A) 1 hour B) 2 hours C) 1 hour 30 minutes D) 2 hours 30 minutes

Discuss

Answer & Solution

Time spend in C = 15%
Time spend in G = 10%
∵ 15% = 3H
∴ 10% = $$\frac{3}{15}$$ × 10 = 2 hours
