If the Price of 6 toys is Rs. 264.37, What will be the approximate price of 5 toys?

Correct Answer: 32

Explanation:

(Men 14 : 16) : (Hrs/Day 12 : 7) :: 48 : x
14 * 12 * x = 16 * 7 * 48 or x = 32

Correct Answer: 6 hours a day

Explanation:

More Men, Less Hours {Indirect Proportion}

Less Days, More Hours {Indirect Proportion}

  m e n 15 : 10 d a y s 12 : 18 ? ? 6 : x

 

=> 15 * 12 * x = 10 * 18 * 6

=>x = 6

Correct Answer: 16

Explanation:

Let the required number of bottles be x.

 

More weavers, More mats (Direct Proportion)

 

More days, More mats (Direct Proportion)

 

 

$$\begin{gathered} w e a v e r s 4 : 8 } : 4 : x \\ d a y s 4 : 8 } : 4 : x \end{gathered}$$ 

4 x 4 x x = 8 x 8 x 4

 

=> x =  8 * 8 * 4 4 * 4

 

=> x = 16.

Correct Answer: 40

Explanation:

Let the required number of days be x.

 

Less cows, More days (Indirect Proportion)

 

Less bags, Less days (Direct Proportion)

 

$$\begin{gathered} c o w s 1 : 40 : 40 : x \\ b a g s 40 : 1 : 40 : x \\ \end{gathered}$$

 

1 x 40 x x = 40 x 1 x 40

 

=>  x = 40.

Correct Answer: 48 Paise

Explanation:

Let the Required cost be X paise.  Less Weight , Less cost (Direct Proportion)

Therefore, 250 : 200 :: 60 : x

=> (250 * x) = (200 * 60)

=> x= 48

Correct Answer: 45.61 sec

Explanation:

Given loom weaves 1.14 mts of cloth in one second then 52 mts of cloth can be weaved by loom in,

1.14 ----- 1

52.0 ------?

  ? 52 1 . 14= 45.61 sec

Correct Answer: 30

Explanation:

There is a meal for 200 children. 150 children have taken the meal.

 

Remaining meal is to be catered to 50 children.

 

Now, 200 children = 120 men.

 

50 children = 120 200 50 =30men

Correct Answer: 195 seconds

Explanation:

Let the time required by x seconds.

Then, More cloth means More time (Direct Proportion)

So, 0.128 : 1 :: 25 : x

? x = 1 × 25 0 . 128 => x = 195.31

 So time will be approx 195 seconds

Correct Answer: 144

Explanation:

Less toys, Less Price (Direct Proportion)
So, let the price be Rs. x
then,

             23:12::276:x    => x=(276*12)/23

                                    => x=144

So price of 12 toys will be Rs. 144

Correct Answer: 3109

Explanation:

Time = 2 years 4 months = 2(4/12) years = 2(1/3) years.
Amount = Rs'. [8000 X (1+(15/100))^2 X (1+((1/3)*15)/100)]
=Rs. [8000 * (23/20) * (23/20) * (21/20)]
= Rs. 11109. .
:. C.I. = Rs. (11109 - 8000) = Rs. 3109.
