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).
