A taxi company charges $1.15 for the first quarter of a mile and fifteen cents for each additional quarter of a mile. What is the maximum distance someone could travel with $4.90? | [
"5 1/2 miles",
"4 1/4 miles",
"6 1/2 miles",
"4 miles"
] | C | If we start out with $4.90 and have to spend $1.15 for the first quarter-mile, we will have $3.75 left to spend on quarter-mile intervals.
Since $3.75/$0.15 = 25, we can buy 25 more quarter-miles, and will travel 26 quarter miles in all:
26 × 1/4 = 6 1/2 miles.
The correct answer is choice (E). | AquaRat_train |

The avg weight of A,B & C is 84 kg. If D joins the group, the avg weight of the group becomes 80 kg.If another man E who weights is 7 kg more than D Replaces A, Then the avgof B,C,D&E becomes 79 kg. What is the weight of A? | [
"75",
"79",
"25",

] | B | A + B + C = 3 *84 = 252
A + B + C + D = 4 * 80 = 320 ---- (i)
So, D = 68& E = 68 + 7 = 75
B + C + D +E = 79 * 4 = 316 --- (ii)

A-E = 320 – 316 = 4
A = E +4 = 75 + 4 = 79

"27",
"22",
"48",
"99"
] | C | Explanation: Simple one. Let the total work to be done is 48 meters. Now Jake can dig 3 mts, Paul can dig 2 mts a day. Now all of them combined dug in 8 days so per day they dug 48/8 = 6 mts. So Of these 8 mts, Hari capacity is 1 mt.
So he takes 48 /1 = 48 days to complete the digging job.

Explanation:
Total age of 10 persons = 10 × 32 = 320
Total age of 11 persons = 11 × 36 = 396 (as the new average is 4 more than present average)
So the age of the person joining is = 396 - 320 = 76
