In the first case,
A milkman sold one of his Buffaloes for 20000 rupees. On this he made a gain of 5%.
Using ratio and percentage concept, we can express the fact in the following way:
SP/CP = 105/100 ( CP being 100)
105 unit = 20,000 rupees
100 unit = (20000/105) × 100 = 19047.61 rupees.
Hence, CP in this case is 19047.61 rupees.

Similarly, In the second case,
SP/CP = 90/100
100 unit = 20000
90 unit = (20000/100) × 90 = 18000
CP is 18000.

Total CP= (18000 +19047.61) = 37047.61
Total SP =(20000+20000)= 40000
CP<SP, gain is incurred.
Gain % = (Gain/ CP) ×100
Gain% =( 2952.39 / 37047.61) ×100 = 7.97 % is the required answer.
