5. Of the 1500 seats in Shatabdi Express, 80% are Chair cars while the remaining make up the Executive Class. During one journey, the train was booked to 85% of its capacity. How many Chair Car seats were empty during the journey if 96% of the Executive Class seats were booked?

1. 216
2. 211
3. 213
4. None of these  

   Solutions

1 Let speed of train A, s = 90kmph

 = 90*(5/18) m/s = 25 m/s

Time taken by train A, t = 36s

Length of train A, L’ = t*s = 36*25 = 900m

Therefore, Length of train B, L” = 900-100 = 800m

Speed of train B, s’ = 45*(5/18) = 25/2 m/s

Time taken by train B, t’ = (distance/speed) = 800÷(25/2) = 1600/25

=64 seconds

2. 600 men dig 5.5*4*405 = 8910 cu.m. in half an hour

600 men dig 106920 cu.m. in 6 hours

2500 men dig 445500 cu.m. in 6 hours            [(106920/600)*2500]

Again, 2500 men dig (8*10)x cu.m. in 6 hours [where x = length of canal ]

(8*10)x = 445500

X = 445500/80 = 5568.75 m

3. Total population = 2,96,000

Males = 1,66,000

Females = 1,30,000

Literate males = 60% of (166000) = 99,600

Now 50% of total population is literate

So, literate females = (50% of 296000)-99600 = 48400

4. Total mass of grapes in 250 kg of dry grapes = 85% of 250 kg = 212.5 kg

Since 75% of fresh grapes is water, 212.5 kg will be 25% of fresh grapes

So, total weight of fresh grapes = 212.5*(100/25) = 850 kg

 5. Total no. of seats = 1500

No, of seats in Executive Class = 300

No. of seats in Chair Car = 1200

Total seats occupied = 85% of 1500 = 1275

Total seats occupied in Executive Class = 96% of 300 = 288

Total seats occupied in the chair car = 1275-288 = 987

Therefore, no. of seats vacant in the chair car = 1200-987 = 213

1. 45.83%
2. 47.62%
3. 46.77%
4. 47.28%

Ans: 47.62%

Solutions

1)20% + (1-(0.3+0.2+0.1)) =20%+40% = 60% is either made up of bones or hormones.

Hence, the rest of the 40% weight of the body is made up of neither.

2) 20% + (1-(0.3+0.2+0.1)) =20%+40% = 60% is either made up of bones or hormones.

3)10/21 = 47.62%

4)Cannot be determined

5)In the evening, the sun sets in the west. Hence the shadows will fall in the east direction. Since Sushma’s shadow was to the right of her, she was facing north. Thus Jaya was facing the South.
