A) 1320 kg B) 440 kg C) 880 kg D) 1760 kg

Answer 1

Answer:

8.8 kg

Step-by-step explanation:

Given:

= x + ( 1 - 23 / 100 ) + ( 22 - x ) ( 1 + 3 / 100 ) = 22 ( 1 + 27 / 100 ).

= x ( 123 / 100 ) - x ( 133 / 100 ) + ( 22 × 133 ) / 100 = ( 22 × 127 / 100 ).

Then

→ 10x / 100 + 2926 / 100 = 2794 / 100

→ 10x / 100 = 2794 / 100 - 2926 / 100

→ 10x / 100 = - 132 / 100

→ x = 132 / 10 = 13.2 kg

Now 22 - x = 33 (%)

33% is the profit percentage.

→ 22 - x = 33%

→ 22 - 13.2

→ 8.8 kg

Therefore, 8.8 kg is the weat sold at 33% profit.
