Let total be x

30%of x=3x/10

Remaining =x-3x/100=7x/10

70% of 7x/100=49x/100

Still remaining =1050

Total =(3x/10)+(49x/100)+1050

x=(30x+49x)/100+1050

x=79x/100+(105000/100)

x=(79x+105000)/100

100x=79x+105000

21x=105000

x=5000

Answer:

Step-by-step explanation:Let total be x

30%of x=3x/10

Remaining =x-3x/100=7x/10

70% of 7x/100=49x/100

Still remaining =1050

Total =(3x/10)+(49x/100)+1050

x=(30x+49x)/100+1050

x=79x/100+(105000/100)

x=(79x+105000)/100

100x=79x+105000

21x=105000

x=5000
