"7/6",
"7/2",
"7/8",
"7/7"

7/8 = 70/80; 13/16 = 65/80; 31/40 = 62/80
Since, 70/80 > 63/80 > 65/80 > 62/80,
So, 7/8 > 63/80 > 13/16 > 31/40
So, 7/8 is the largest.

"1105.26",
"1103.26"

Let the new selling price be Rs. x
(100 – loss %) /1000 = (100 + gain %) / x
(100 – 5) / 1000 = (100 + 5) / x
x = (105 × 1000) / 95 = 105000 / 95

To deliver an order on time, a company has to make 25 parts a day. After making 25 parts per day for 3 days, the company started to produce 5 more parts per day, and by the last day of work 100 more parts than planned were produced.How many parts the company made? | [
"654",
"589",
"412",
"675"
] | D | Let x be the number of days the company worked. Then 25x is the number of parts they planned to make. At the new production rate they made:
3⋅25+(x−3)⋅30=75+30(x−3)
Therefore: 25x=75+30(x−3)−100
25x=75+30x−90−100
190−75=30x−25
115=5x
x=23
So the company worked 23 days and they made 23⋅25+100=675 pieces.

What is the largest possible value of cc if 5c+(d−12)^2=235? | [
"35",
"42",
"17",
"47"
] | D | To maximize c, we should minimize (d-12)^2. (d-12)^2 is a square of a number, thus its smallest possible value is 0 (for d = 12).
In this case we'd have 5c + 0 = 235 --> c = 47.

2) An bus covers a certain distance at a speed of 240 kmph in 5 hours. To cover the samedistance in 1hr, it must travel at a speed of? | [
"740 km/hr",
"720 km/hr",
"700 km/hr",
"780 km/hr"
] | B | Distance = (240 x 5) = 1200 km.
Speed = Distance/Time
Speed = 1200/(5/3) km/hr. [We can write 1 hours as 5/3 hours]
Required speed = 1200 x 3 km/hr = 720 km/hr.

Students at a school were on average 180 cm tall. The average female height was 170 cm, and the average male height was 188 cms. What was the ratio of men to women? | [
"3:1",
"5:4",

1) The average height of the females is 170cm
2) The average height of the males is 188cm
3) The average of the GROUP is 180cm
We're asked for the RATIO of men to women.
W = number of Women
M = number of Men
(170W + 188M)/(W+M) = 180
170W + 188M = 180W + 180M

Then, speed of train = 180⁄18 = 10 m/s
Now, length of train = 10 × 15 = 150m
∴ Required time = 150⁄10 = 15 sec.
