so he totally gave 60% out which remained 40% with him from the question it means that 9600 is the remaining percent he has which is 40%. So we need to calculate which values 40% is equal to 9600 [tex] \frac{40}{100} x = 9600[/tex] [tex]x = 9600 \div \frac{40}{100} [/tex] [tex]x = 9600 \times \frac{100}{40} [/tex] so [tex]x = 24000[/tex] since 40% of 24000 is 9600 it means he had 24000 in total/originally comment with me if you still don't understand
