Question

Pl help and explain in detail ​

Answer 1

Answer:

A/q

Total number of people=1000

Adults+boys+girls=1000

Adults=1000-(boys+girls)

         =1000-(x+y)

Total money paid by adults= 10(1000-x-y)

                                             =10000-10x-10y

Total money paid by boys and girls= 5x+5y

Total money paid= 5x+5y+10000-10x-10y

                            =  10000-5x-5y

                            =   5(2000-x-y)

Hence Right answer is last ( D).
