A bread merchant declares a 15% discount after 8 P.M. Ana goes before 8 P.M. with Rs.50 in her pocket to buy 3 pieces of bread and got some change. Tom goes after 8 P.M. with Rs.40. How many pieces of bread can Tom buy at the most? | [
"2",
"5",
"4",
"3"
] | A | At the most, a piece of bread costs 50/3 = 16.67 before 8 P.M.
After 8 P.M., each piece of bread will now cost (1 - 15%) * 16.67 = 0.85 * 16.67 = 14.17
Since Tom has Rs.40, 40 / 14.17 = 2.82
Since you cannot buy half pieces of bread, at the most, Tom can buy 2 pieces of bread after 8 P.M.

A car owner buys petrol at Rs 7.50, Rs. 8 and Rs. 8.50 per litre for three successive years. What approximately is the average cost per litre of petrol if he spends Rs. 4000 each year ? | [
"7.99",
"7.98",
"7.9",
"7.92"
] | B | Explanation:
Total quantity of petrol consumed in 3 years = liters
= liters
= liters
Total amount spent = Rs. (3 x 4000) = Rs. 12000.
Average cost = Rs. = Rs. 7.98.

The toll T, in dollars, for a truck using a certain bridge is given by the formula T = 2.50 + 0.50( x − 2), where x is the number of axles on the truck. What is the toll for an 18-wheel truck that has 2 wheels on its front axle and 4 wheels on each of its other axles? | [
"$ 3.00",
"$ 4.00",
"$ 3.50",
"$ 5.00"
] | B | Number of wheels in truck = 18
Number of wheels on its front axle =2
number of wheels remaining = 16
number of axles remaining axles = 16/4 = 4
Total number of axles = 5
T = 2.50 + 0.50( x − 2)
= 2.50 + .5*3

The length and breadth of a rectangle are raised in the proportion 3:4 and 4:5 correspondingly. What is the proportion of the previous place to the new? | [
"5:7",
"2:3",
"3:5",
"None of these"
] | C | Explanation :
-> If the real length = 3a
And the real breadth = 4a
Area = (3a)*(4a)
=12 a2
-> New Length is 4a and New breadth is 5a
New area is (4a)*(5a)
= 20 a2
Ratio of previous place to new place = 12 a2 : 20 a2
= 12 : 20
= 3 : 5

Time to cover 1 kilometer at regular speed is 45 + 4 = 49 seconds = 49/3,600 hours = 1/74 hours;
So, we get that to cover 1 kilometer 1/74 hours is needed --> regular speed 74 kilometers per hour (rate is a reciprocal of ... | AquaRat_train |

Rolling dices is an independent event.
The combinations to get 8 are (1,7), (7,1), (2,6), (6,2), (3,5), (5,3), (4,,4) and total combinations of both dices is 49.
The probability of getting 8 in first attempt is 7/49=1/7.
Probability of getting 8 again in second attempt = (1/7)*(1/7) = 1/49. ANS E | AquaRat_train |
