Question

For A and B the ratio of cost price is 4:5 and ratio of
selling price is 4:7. The ratio of total cost price and
total selling price is 45:44 and the net loss is Rs 20.
What is the difference between their selling prices?​

Answer 1

Answer:

240

Step-by-step explanation:

Ratio method is the fastest approach to this problem

total CP:SP given as 45:44 ----- difference is 1 unit

so, 1 unit----- 20 rs

total SP ---- 44 unit = 44 x 20 = 880rs

selling price ratio = 4:7

so 4+7 units = 11 units which is = 880rs

so 1 unit =80rs

asked difference between SP is 7-4 = 3units

which is 3 x 80rs = 240rs

240 is the answer

Step-by-step explanation:

c1/c2=4/5

c1/c2=4/5c1+c2=4x+5x=9x

c1/c2=4/5c1+c2=4x+5x=9xlike above selling price ratio is s1+s2=11y

c1/c2=4/5c1+c2=4x+5x=9xlike above selling price ratio is s1+s2=11yand given c1+c2=45z

c1/c2=4/5c1+c2=4x+5x=9xlike above selling price ratio is s1+s2=11yand given c1+c2=45zand s1+s2=44z

c1/c2=4/5c1+c2=4x+5x=9xlike above selling price ratio is s1+s2=11yand given c1+c2=45zand s1+s2=44zand 45z-44z=20 and z=20

c1/c2=4/5c1+c2=4x+5x=9xlike above selling price ratio is s1+s2=11yand given c1+c2=45zand s1+s2=44zand 45z-44z=20 and z=20and s1+s2=44*20

c1/c2=4/5c1+c2=4x+5x=9xlike above selling price ratio is s1+s2=11yand given c1+c2=45zand s1+s2=44zand 45z-44z=20 and z=20and s1+s2=44*20and 11y=44z

c1/c2=4/5c1+c2=4x+5x=9xlike above selling price ratio is s1+s2=11yand given c1+c2=45zand s1+s2=44zand 45z-44z=20 and z=20and s1+s2=44*20and 11y=44zy=80, and i f you submit this in second ration of qn
