Answer: Option A

Explanation:

school A has a boys and b girls, and school B has c boys and d girls, then

a/c = 2/1
b/d = 4/5
a+b = c+d

we want to find a/b

a = 2c
5b = 4d

a-c = d-b
a-(a/2) = (5b/4)-b
a/2 = b/4
a/b = 2/4 = 1/2

View Answer	Favorite Question

Answer: Option D

Explanation:

Let, the number be x

2/5 of 1/4 of 3/7 of x = 15

2/5×1/4×3/7× = 15

6x/140 = 15

6x = 15×140

6x = 2100

x = 350

Half of x is 175

Answer: Option A

Explanation:

Red socks = 2/5 of total

Blue socks = 1/3 of total

Rest are green, so green socks

= 1 - 2/5 + 1/3

= 1 - (6 + 5)/15

= 1 - 11/15

= (15 - 11)/15

= 4/15 of total

Hence, ratio of green to blue socks

= 4/15 : 1/3

= 4 : 5

So, the correct answer choice is option 1

3323 . Two-fifths of the socks in box are red, one-third is blue and the rest are green. What is the ratio of the green socks to the blue socks?

Blue socks = 1/3 of total

Rest are green, so green socks

= 1 - 2/5 + 1/3

Hence, ratio of green to blue socks

= 4/15 : 1/3

= 4 : 5

So, the correct answer choice is option 1

3325 . Two identical tapes fill 2/5 of a tank in 20 minutes. When one of the taps goes dry in how many minutes will the remaining one tap fill the rest of the tank?

A. 5 minutes
B. 10 minutes
C. 60 minutes
D. 20 minutes

View Answer	Favorite Question

Answer: Option C

Explanation:

Each tap takes 2x20*5/2 = 100 minutes to fill the tank.

In the first 20 minutes, the taps filled 2/5th of the tank. The remaining 3/5th of the tank will take a single tap (3/2)*20*2 = 60 minutes.

3326 . Two identical taps fill 2/5 of a tank in 20 minutes.when one of the taps goes dry n how many minutes will the remaining one tap fill the rest of the tank?

A. 5 min
B. 10 min
C. 60 min
D. 20 min
E. None of these

View Answer	Favorite Question

Answer: Option C

Explanation:

2 taps can fill in 20 minutes = 2/5th

1 tap can fill in 20 minutes = 1/5th.

remaining portion to be filled up = 1 - 2/5 = 3/5.

1/5th can be filled by 1 tap in 20 mins

3/5th can be filled by 1 tap in 20x3 mins = 60 minutes. (ans)

View Answer	Favorite Question

Answer: Option B

Explanation:

Let the two numbers be 3x and 5x respectively.
According to the given problem,
(3x - 9)/(5x - 9) = 12/23
= > 23 × (3x - 9) = (5x - 9) × 12
= > 69x - 207 = 60x - 108
= >9x = 207 - 108
= >x = 99/9 = 11
Therefore, the two numbers are (3 × 11) = 33 and (5 × 11) = 55.
The smaller number is 33.

Answer: Option D

Explanation:

Let's set up the equation based on the given information:

5% of M + 4% of N = (2/3) * (6% of M + 8% of N)

Now, let's simplify and solve for the ratio of M and N.

First, convert percentages to decimals:

0.05M + 0.04N = (2/3) * (0.06M + 0.08N)

Now, eliminate the fractions by multiplying both sides by 3 (the least common multiple of 3 and 2):

3 * (0.05M + 0.04N) = 2 * (0.06M + 0.08N)

Now, distribute on both sides:

0.15M + 0.12N = 0.12M + 0.16N

Next, let's isolate terms with M and N on different sides of the equation:

0.15M - 0.12M = 0.16N - 0.12N

0.03M = 0.04N

Now, divide both sides by 0.03 to find the ratio of M and N:

(M/N) = (0.04N) / 0.03M

(M/N) = (4/3) * (N/M)

Now, simplify the ratio:

(M/N) = 4/3

So, the ratio of M to N is 4:3. The correct answer is 4:3.
