A baker filled with a measuring cup with 3/4 cup water. He poured 1/2 of the water into the batter, and then spilled 3/8 of the water on the floor. How much water will the baker needed to add what is left in the cup to have 50% more than what he started with? | [
"1/8 cup",
"3/8 cup",
"1/4 cup",
"9/8 cup"
] | D | 3/4 is the original water in cup .half in batter.So left is 3/8 out which 3/8 is spilled out.So again left with 0/8.
so 50% more than what he started was = 3/4+1/2*(3/4)=9/8
Amount of water needed to add = 9/8 - 0/8=9/8

The sum of the two digits of a number is 10. If the number is subtracted from the number obtained by reversing its digits, the result is 54. Find the number? | [
"27",
"20",
"76",
"28"
] | D | Any two digit number can be written as (10P + Q), where P is the digit in the tens place and Q is the digit in the units place.
P + Q = 10 ----- (1)
(10Q + P) - (10P + Q) = 54
9(Q - P) = 54
(Q - P) = 6 ----- (2)
Solve (1) and (2) P = 2 and Q = 8
The required number is

When twice the original number is divided by the same divisor, the remainder is 11. What is the value of the divisor? | [
"34",

A bus covered a distance of 250 km, partly at an average speed of 40 kmph and partly at 60 kmph. If the total time taken is 6.5 hours, then the distance covered at 40 kmph is | [
"120km",
"100km",
"280km",
"none of these"
] | C | Let the partial distance covered at 40 kmph be X
Let the another partial distance covered at 60 kmph be (250 - x)
Thus, x/40 - (250 - x)/60 = 6.5
or, x/40 + (250 - x)/60 = 6.5
or, (3x + 500 - 2x)//120 = 6.5
