Let the total work be 96 units Efficiency of Meena = 96/32 = 3 units/day Efficiency of Sanju = 96/48 = 2 units/day Suppose Meena and Sanju worked together for x days Worked done by them = 5x Remaining work = 96 – 5x Now, this work is completed by Sanju in 24 days According to the question, ⇒ 2 = (96 – 5x) /24 ⇒ 48 = 96 – 5x ⇒ 48 = 5x ⇒x=
