Let the number of boys be B.
Then, number of girls = 2B.
? B + 2B = 60
or 3B = 60
or B = 20.
So, number of boys = 20 and number of girls = 40.
Number of students behind Kamal in rank (60 ? 17) =43.
Number of girls ahead of Kamal in rank = 9.
Number of girls behind Kamal in rank = (40 ? 9) = 31
? Number of boys behind Kamal in rank = (43 ? 31) = 12.
Total days from 25th June to 15th August = 5 + 31 + 15 = 51 days = 7 weeks and 2 days
August 15 = Wednesday + 2 = Friday
Given :- The third day of a month is Tuesday
i.e. 3rd ? Tuesday
Other Tuesday ? 10th; 17th; 24th
? 25th ? Wednesday
Required day will be Wednesday .
Here ,Today is Friday + 2, i.e., Sunday.
Tomorrow will be Monday.
? The Day after tomorrow will be Tuesday and two days after Tuesday will be Thursday.
If the day before yesterday was Thursday
Today is Thursday + 2 days = Saturday
Therefore, tomorrow will be Sunday.
According to question,
Mohini goes to movies only on Thursday. she went nine days back to movies. Then 9 days back it was Thursday.
7th day will be Thursday , then 8th day will be Friday and 9th day it means today will be Saturday.
According to given question,
If the positions of the first and the sixth digits of the group of digits 5904627813 are interchanged.
New number after interchange = 2904657813
Then the positions of the second and the seventh are interchanged.
New number after interchange = 2704659813
fourth from the right end after the rearrangement is 9.
In the original group of digits '7' is fourth from the right, which is interchanged with '9'.
According to question,
'P' is neither as tall as 'M' nor as short as 'O'.
M > P > O .............................(1)
'N' is shorter than 'P' but taller than 'O'.
P > N > O...............................(2)
After comparing the equation (1) and (2),
we will get,
M > P > N > O
The correct order of dolls according to descending order of their heights are : M > P > N > O.
Therefore, Anvi will purchase the doll M.
Total boys = [ Malay's place from starting + Malay's place from end ] ?1
Total boys = [13 + 17] ? 1 = 29
Number of passed students = [ Malay's place from starting + Malay's place from end ] ?1
Number of passed students = [8 + 13] ? 1= 20
? Number of failed students = 29 ? 20 = 9
