aquarat_20162 | aquarat | The cost of a car is 400% greater than the cost of a bike. If there is an increase in the cost of the car is 15% and that of bike 20%. Then the total increase in the cost of the 5 cars and 10 bikes is: | [
"A)17.5%",
"B)16(3/7)%",
"C)18.5%",
"D)18.25%"
] | B | Solution: Let the bike's initial cost be X and then car's initial cost be 5X.
After the increase,
Bike price = 1.2X
Car price = 5.75X
Initial total cost of 5 cars and 10 bikes,
= 25X+10X = 35X
New cost,
= 28.75X+12x = 40.75X
Change in cost = (40.75X-35X) = 5.75X
% change = (5.75X*100)/35 = 16(3/7)%.

"A)49.5m",
"B)46 m",
"C)49 m",
"D)46.5m"
] | C | Let the required length be x metres
More men, More length built (Direct Proportion)
Less days, Less length built (Direct Proportion)
Men 20: 35
Days 6: 3 : : 56 : x
Therefore (20 x 6 x x)=(35 x 3 x 56)<=>x=(35 x 3 x 56)/120=49
Hence, the required length is 49 m.
