Explanation:

-> If “a” be the count of guys and “b” be the count of gals.
Total count of guys and gals = 100
a + b = 100 —Eqn(i)
-> A guy gets Rs.3.60 and a gal gets Rs. 2.40
The money given to 100 guys and gals = Rs. 312
3.60a +2.40b = 312 —Eqn(ii)
->Solving (i) and (ii)
a 3.60 => 3.60 a + 3.60b = 360 (-)
=> 3.60 a + 2.40b = 312
1.20b = 48
B = 48 / 1.20 = 40
Therefore, Count of gals = 40
