Suppose that his salary = Rs. 100
House Rent = Rs.10
so, Balance = Rs. 90
Expenditure on education = Rs. (15 x 90) / 100= Rs.13.50
Balance =Rs.76.50
Expenditure on clothes = Rs.(10 x 76.50) / 100 = Rs. 7.65
Balance now = Rs.68.85
If balance is Rs. 68.85, salary =Rs. 100
If balance is Rs. 1377, salary = Rs.(100/68.85) x 1377 = Rs. 2000
Clearly, if A runs 600 meters, B runs = 540 m.
? If A runs 400 m, B runs = 540 x 400 / 600 = 540 x 4 / 6 = 90 x 4 = 360 m
Again, when B runs 500 m, C runs = 450 m
? When B runs 360 m, C runs = 450 x 360 / 500 = 45 x 36 / 5 = 9 x 36 = 324 m.
? A beats C by 400 - 324 = 76 m.
36.98276421 x 21.00002
Using nearest value in whole number for 36.9827421 is 37 and 21.0002 is 21
? 37 x 21 = 777 ? 775
= Unit digit in [(42)896 x 4]
= Unit digit in (6 x 4) = 4
Unit digit in (625)317 = Unit digit in (5)317 = 5
Unit digit in (341)491 = Unit digit in (1)491 = 1
Required digit = Unit digit in (4 x 5 x 1) = 0.
Speed of the train relative to man | = (63 - 3) km/hr | |||||||

Unit digit must be 0 or 5 and sum of digits must be divisible by 9.
Among given numbers, such number is 202860.
Then, x = 7589 - 3434 = 4155
At 11 : 50 A.M. from the formula here P = 11 and Q = 50 so required angle is 11 x 50/2 - 30 x 11 = 275 - 330 = -55 or ignoring the negative sign the required angle is 55°
