Question

please answer 17 and 20 who will give right answer will be brainiest

Answer 1

17. let the original price be x
s.p = c.p + profit
= x+.2x
=1.2x
1.2x= 750
x= 625(a)
20. let c.p = x
s.p(Mr.Q) = 0.9x= c.p of(Mr.A)
s.p(Mr.A) = .2*0.9x +0.9x= 1.08x= c.p(Mr.V)
1.08x= 82440
x= 76333(b) ans

Answer 2

sp={(100+20 )/100}×cp
750=(120/100)*co
750*100/120=cp
cp=625
