Fill in the blanks.
• There were 40 children at a party. 14 of them were boys. __P__ fraction of children were girls.
• Cost of a teddy bear is 
of the cost of a doll. If cost of the teddy bear is ₹ 114, then cost of the doll is ₹ __Q__ .
• Difference between 
is __R__.
• If 
then x = __S__.
| P | Q | R | S | |
| A | 7/20 | 76 | 5/8 | 1/4 |
| B | 13/20 | 76 | 7/8 | 1/4 |
| C | 7/20 | 171 | 5/8 | 3/4 |

Answer is D). How? So let’s hear the question and answers fill in the blanks.
• There were 40 children at a party. 14 of them were boys. __P__ fraction of children were girls.
• Cost of a teddy bear is of the cost of a doll. If cost of the teddy bear is ₹ 114, then cost of the doll is ₹ __Q__ .
• Difference between is __R__.
• If then x = __S__.
P Q R S
A 7/20 76 5/8 1/4
B 13/20 76 7/8 1/4
C 7/20 171 5/8 3/4
D 13/20. 171 7/8 3/4
So the first question is.
• There were 40 children at a party. 14 of them were boys. __P__ fraction of children were girls.
So the answer is 26/40 or 13/20 because if there are 14 boys out of 40 children then 26 girls out of 40 children answer for the first question is 26/40 or 13/20.
So option A) and C) cannot be the answer because they are not equivalent to 26/40 or 13/20. Now let’s hear the second question.
• Cost of a teddy bear is of the cost of a doll. If cost of the teddy bear is ₹ 114, then cost of the doll is ₹ __Q__ .
So the cost of the doll is ₹171 because cost of a teddy bear is 2/3 cost of a doll And the cost of the teddy bear is also equal to ₹114 so how get answer as ₹171 you have to divide ₹114 by 2 to get 1/3 of cost of the doll and then we ₹57, and then we multiply ₹57 by 3 to get the cost of the doll answer is ₹57 + ₹57 + ₹57 = ₹114 + ₹57 or ₹171. Now the option B) cannot be the answer because it is not equivalent to ₹171. Now you’ll are thinking that why I didn’t show the explanation of questions 3 and 4. I did not show you questions 3 and 4 because there are only 4 options and in answers none of the options none of these as their answers. Hence we have an answer which is D).
from 
and then multiply the result by the multiplicative inverse of
