need clarification. (Question: 97550.0 )

how can you say it is 50 and 100 it lso can be 20 and 70, 30 and 80, 40 and 90.
? plz clear the concept.

Question:
\(\unicode{x20B9} \)69 were divided among 115 students so that each girl gets 50  paise less than a boy. Thus each boy received twice the paise as each girl received. The no. of girls in the class is:
Options:
A) 92
B) 42
C) 33
D) 23
Solution:

Ans: (a) Here each girl receives 50 paise and each boy receives 100  paise and the average receiving of each student

= \(\cfrac{6900}{115}\) = 60 paise


⇒ (G) 4  :  (B) 1

Thus the no. of girls = 92                              

[Number of boys = 23]
