Answer: Number of children = 168
Number of adults = 120
Explanation:
Let x = Number of children and y = Number of adults
As per given,
x+y=288 (i)
2.25x+6.80y =1194 (ii)
Multiply 2.25 on both sides in (i)
2.25x+2.25y= 648 (iii)
Eliminate (iii) from (ii)
4.55y=546
Put y= 120 in (i)
x+120=288
⇒ x=288-120
⇒ x= 168
Hence, Number of children = 168
Number of adults = 120
