Answer 1

Answer:

Step-by-step explanation:

240

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
