SSC MTS 6 Aug 2019 Shift 1 Paper

The average weight of 14 children = 22 kg
⇒ Total weight of 14 children = 22 × 14 = 308 kg
⇒ The average weight of 14 children and a teacher = 23 kg
⇒ Total weight of 14 children + weight of teacher = 345
⇒ 308 + weight of teacher = 345
⇒ Weight of teacher = 37 kg
∴ Weight of teacher is 37 kg
