rajeev bought some army day tickets₹5and₹10.if the spet ₹150and bought 18 tickets in all find how many tickets of each kind he bought​

Answer 1

Answer:

There fore , he bought 6 tickets for rs.5 and 12 for rs.10.

Step-by-step explanation:

let rs.5 tickets be x and Rs.10 tickets y.

we know that x+y =18(ticket 1 + ticket 2= total no. of tickets)

5x+10y=150(total money spent).....eq1

x+y=18.....eq2

⇒x=18-y....eq4

(x+y=18)*5= 5x+5y=90......eq3

subtracting eq.3 from 1.

5y=60

y=60/5

y=12

x=18-y.......from eq.4

x=18-12

x=6

There fore , he bought 6 tickets for rs.5 and 12 for rs.10.
