A and B invest in a business in the ratio 3 : 2. If 5% of the total profit goes to charity and A's share is Rs. 855, the total profit is:
A. Rs. 1425 B. Rs. 1500
C. Rs. 1537.50 D. Rs. 1576
Read Solution (Total 6)
-
- A:B=3:2
A's share=855 so, B's share= 2/3 0f 855=570
total a+b share = 855+570=1425
and it 95% of the profit as 5% goes to charity
hence total profit was 1425*100/95= 1500 - 12 years agoHelpfull: Yes(15) No(4)
- option: B
A:B=3:2
Let totsl profit be x
A's share=855 so, B's share= 2/3 0f 855=1425
x=855+1425+5%0fx
or, x=1500 - 12 years agoHelpfull: Yes(5) No(8)
- Do directly by ratio method
First calculate x-5% x=95x/100
95x/100=855 + y ( let share of B be y)
Calculate ratio:
3/2=855/y or
3/2=855/(95x/100 -855)
=1500 - 9 years agoHelpfull: Yes(1) No(0)
- let total profit=x
Given, a:b=3:2 And A share=855
5% profit goes to charity.Therefore renaming =x-(5/100)*x=19x/20
therefore, 3/5*19x/20=855 =>x=1500
so total profit=1500(ans)

- profit=285*(5/3)=1425
total profit(tp)=(5/100)*tp+1425
(95*tp/100)=1425
tp=1500
