Then, speed of the train = | 150 | x | = | ❨ | 3 | x | ❩kmph. |
100 | 2 |
∴ | 75 | - | 75 | = | 125 |
x | (3/2)x | 10 x 60 |
⟹ | 75 | - | 50 | = | 5 |
x | x | 24 |
⟹ x = | ❨ | 25 x24 | ❩ | = 120 kmph. |

We have the important relation, More work, More time (days)
? A piece of work can be done in 6 days.
? Three times of work of same type can be done in 6 x 3
= 18 days
? = 750.0003 ÷ 19.999
? ? ? 750 ÷ 20
? ? ? 375 ? 38
Subtract 20, 25, 30, 35, 40, 45 from successive numbers. So 0 is wrong.
NA
Each previous number is multiplied by 2.
? 8 m shadow means original height = 12 m
? 1 m shadow means original height = 12/8 m
? 100 m shadow means original height = (12/8) x 100 m
= (6/4) x 100 = 6 x 25 = 150 m
Let 8% of 96 = y of 1/25
? (8 x 96)/100 = y/25
? y = (8 x 96 x 25)/100 = 192
Since the principal is not given, so data is inadequate.
