                                                                                                        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). 
                                                                                                    
                                                                                                    Post Your Answer
