Question

10.80₹divided among 45 girls and boyes that every boyes get 22 paisa and every girls get 28 paisa so how many boyes and girls get it?

Answer 1

let the no. of  boys be b and let the no. of girls be g..according to the question,
b + g=45.............eqation 1
and (22b+28g)=1080 .............eqn.2
now,multiplying eqn.1 with 22,we get
22b+22g=990..............eqn.3
now subtracting eqn. 3 from eqn.2, we get
5g=1080-990
    =90
g=90/5=18
b=45-18
=27
Hence,the total no. of boys is 27 and girls is 18...
