Lake A has a duck population of 30 females and 36 males. Lake B’s duck population consists of the same ratio of females to males. If 4 new female ducks are added to Lake B and no other ducks are added or removed, the new total duck population of Lake B could be which of the following? | [
"75",
"144",
"36",
"78"
] | A | Lake A has a duck population of 30 females and 36 males --> the ratio is F:M = 30:36 = 5:6.

A man's speed with the current is 21 km/hr and the speed of the current is 2.5 km/hr. The man's speed against the current is? | [
"10",
"30",
"20",
"16"
] | D | Man's speed with the current = 21 km/hr
=> speed of the man + speed of the current = 21 km/hr
speed of the current is 2.5 km/hr
Hence, speed of the man = 21 - 2.5 = 18.5 km/hr
man's speed against the current = speed of the man - speed of the current
= 18.5 - 2.5 = 16 km/hr

The ball bounces differently, and shoes slip on some surfaces but stick on others. These differences are a result of friction. | SCiQ_train |
A certain company employs 5 senior officers and 4 junior officers. If a committee is to be created, that is made up of 3 senior officers and 1 junior officer, how many different committee are possible? | [
"210",
"40",
"8",
"58"
] | B | Number of ways to select 3 senior officers from 5 of them = 5C3 = 10 ways
Next we can determine the number of ways to select 1 junior officer.
number of ways to select 1 junior officer from 4 of them = 4C1 = 4 ways
Thus the number of ways to select 3 senior officers and 1 junior officer is 10 x 4 = 40 ways.

"150m",
"380m",
"350m",
"350m"
] | C | Speed = [300 / 18] m/sec = 50/3 m/sec.
Let the length of the platform be x meters.
Then, x + 300 / 39 = 50/3

An order was placed for the supply of a carpet whose breadth was 6 m and length was 1.44 times the breadth. What be the cost of a carpet whose length and breadth are 40% more and 25% more respectively than the first carpet. Given that the ratio of carpet is Rs. 45 per sq m? | [
"4882.40",
"9082.40",
"8082.40",
"4082.40"
] | D | Explanation:
Length of the first carpet = (1.44)(6) = 8.64 cm
Area of the second carpet = 8.64(1 + 40/100) 6 (1 + 25/100)
= 51.84(1.4)(5/4) sq m = (12.96)(7) sq m
Cost of the second carpet = (45)(12.96 * 7) = 315 (13 - 0.04) = 4095 - 12.6 = Rs. 4082.40

The number 523fbc is divisible by 7,8,9. Then what is the value of f*b*c | [
"280",
"180",
"532",
"210"
] | B | LCM of 7, 8 and 9 is 504, thus 523fbc must be divisible by 504.
523fbc=523000+fbc
523000 divided by 504 gives a remainder of 352.
Hence, 352+fbc=k*504.
k=1 fbc=152 --> f*b*c=10
k=2 fbc=656 --> f*b*c=180
As fbc is three digit number k can not be more than 2.

Mr. Thomas invested an amount of Rs. 13,900 divided in two different schemes A and B at the simple interest rate of 14% p.a. and 11% p.a. respectively. If the total amount of simple interest earned in 2 years be Rs. 3508, what was the amount invested in scheme B? | [
"6408",
"6400",
"6405",
"6406"
] | B | Let the sum invested in scheme A be Rs. x and that in scheme B be Rs. (13900 - x). Then,
(x * 14 * 2)/100 + [(13900 - x) * 11 * 2]/100 = 3508
28x - 22x = 350800 - (13900 * 22)
6x = 45000 => x = 7500
So, sum invested in scheme B = (13900 - 7500) = Rs. 6400.
