- 27
- option3
Clear All
11^2 is factors of given number so it's must a part of given number and =6^2=3^2*2^2 means only 3^2 is present in given no but 3^3 is factor of given no so atleast one 3 must be multiplied.
Therefore smallest value of a is,
11^2*3=121*3=363

The ratio of boys to girls in a class is 7 to 3. Among the options below, an acceptable value for the total number of students in the class is :
- 21
- 50
- 37
- 73
- option2
Clear All
Let number of boys = B
Let total number of students = S
Total number of Girls=S-B
So, we have
B / S-B = 7/3
S-B / B = 3/7
S/B -1 =3/7 => S/B=10/7
B=7S/10
So, S must be multiple of 10. Hence, answer is 50

Let price of gift is x,Total no. Of student is y
10y = x --(1)
Now, only 8 students want to contribute but everyone has to pay 150 more therefore,
8(y+150)= x --(2)
After solving equations (1) & (2), we got, y=600
