Let P worked for x days According to question ⇒`x/32+(x+16)/40` = 1 ⇒`(5x+4(x+16))/160` = 1 ⇒ 5 x + 4x + 64 = 160 ⇒ 9x = 160 – 64 = 96 ⇒`x=96/9=32/3 days P left the work after 32/3 days. Alternate Method; P Q 32 40 LCM = 160 units 5 : 4 For last 16 days, Q alone completed = 4 x 16 = 64 units So remaining is done by both = (160 -64)/(5+4) = 96/9 = 32/3 days Hence P left after 32/3 days.
