Question -
550 × ?% - 150 × 12% = 125
Answer ==>
let '?' be P
then,
550× P% - 150 × 12% = 125
550× P/100 - 150×12/100 = 125
5.5×P - 6×3 = 125
5.5P -18 = 125
5.5 P = 125 + 18
5.5P = 143
P = 143×10/55
P = 13 × 2
P = 26
Checking -
550 × P% - 150 × 12% = 125
Putting P = 26
550 × 26/100 - 150 × 12/100 = 125
5.5 × 26 - 3 × 6 = 125
143.0 - 18 = 125
125 = 125
L•H•S = R•H•S
Hence,
Checked..
