Volume of 48 big books is 48bSruthi wrote: Kindly help with this too

Volume of 60 small books is 60s

48b = 60s

Volume of 10 small and 12 big is 10s + 12b

Volume left in Box A is 48b - (10s + 12b)

since 60s = 48b, therefore 10s = (48/6)b

Volume left in Box A

= 48b - (10s + 12b)

= 48b - ((48/6)b + 12b)

= 48b - (8b + 12b)

= 48b - 20b

= 28b

28 big books
