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).

According to BODMAS or DMAS, first / (divide),then * (multiply), then (add) and then - (subtract). So answer should be: S * R - P Q= 5 x 7 - 2 8= 35 - 2 8= 35 - 10= 25

Answer is B). How? First let’s hear the story given. At 9:15 a.m.,Amit left his house and reached the market 10:20 a.m . After shopping ,he left the market at 11:50 a.m.. he reached back his house at 12:30 p.m.. now let’s hear the question. (it’s written in Roman numerals) (i) How much time did he spent in the market? (ii) How much time did he take to travel to his house from the market? Now let’s hear the answers. (i) (ii) A 1 hr 20 mins 50 mins B 1 hr 30 mins 40 mins C 45 mins 40 mins D 90 mins 50 mins So now the first question was how much time did he spent in the market? The amount of time he spent was between 10:20 to 11:50 a.m. = 1 hour 30 minutes = 90 minutes. So now option A) and option C) because the amount of time in options are not equivalent to 1 hour 30 minutes or 90 minutes. Now let’s hear the second question. How much time did he take to travel to his home? The amount of time he took to travel to his home is between 11:50 a.m.to12:30 p.m. = 40 minutes. So now the option D) cannot be the answer because the amount of time in the option is not equivalent to 40 minutes. Hence the answer is B),because in option B) the amount of time in option B) is equivalent to the amount of time it’s supposed to be.
