Directions (1-5): Pie chart given below shows expenditure of six persons and table given below shows ratio between expenditure on three different products by each person. Study the data carefully and answer the following questions.
Note- Expenditure is considered for food, rent and transportation only.
Q1. Find the difference between expenditure of B on Food to that of C’s on food if expenditure of ‘F’ on Food is Rs. 6750.
Q2. A’s expenditure on transport is what percent more than E’s expenditure on transport?
Q3. Find the average expenditure of A, B and C together on transport if average expenditure of D, E and F together on transport is Rs. 4860.
Q4. Expenditure of B and C on Rent is how much more than expenditure of D and E on Rent if expenditure of F on Rent is Rs. 8100.
Q5. If A’s expenditure on rent is Rs. 8100, then find total expenditure of all six persons together? (in lakh)
Q6. A motorboat went downstream for 28 km and immediately returned. It took the boat twice as long to make the return trip than the downstream trip. If the speed of the river flow were twice as high, the trip downstream and back would take 672 minutes. Find the speed of the boat in still water and the speed of the river flow.
Q7. Two trains pass each other on parallel lines. Each train is 100 metres long. When they are going in the same direction, the faster one takes 60 seconds to pass the other completely. If they are going in opposite directions they pass each other completely in 10 seconds. Find the speed of the slower train in km/hr.
Q8. A train can travel 20% faster than a bus. Both start from the point A at the same time and reach point B 75 km away from A at the same time. But the train stopped for 12.5 minutes while stopping at the stations. Find the speed of the bus in km/hr.
Q9. A train covers certain distance between two places at a uniform speed. If the train moved 10 kmph faster, it would take 2 hours less, and if the train were slower by 10 kmph, it would take 3 hours more than the scheduled time. Find the distance covered by the train.
Q10. A motorboat travelling at a certain speed, can cover 25 km upstream and 39 km downstream in 8 hours. At the same speed, it can travel 35 km upstream and 52 km downstream in 11 hours. The speed of the stream is:
Directions (11-15): Find out the approximate value which should replace the question mark (?) in the following questions.
Note: (You are not expected to find out the exact value)
Q11. 25.05% of 2844.01 + 14.95 × 2400 =?
Q12. 1080.18 ÷ 36 + 187 × 20.05 =?
Q13. 125% of 4875 + 88.005 × 14.995 =?
Q14. 39.05 × 14.95 – 27.99 × 10.12 = (36 +?) × 5
Q15. 158.004 × 4.06 + 20.12% of 849.86 + ? = 950.93
