Q10: 45 students and 6 teachers went on a day trip by train. One ticket per student cost them Rs. 175 and one ticket per teacher cost them Rs. 275. How much money they must have spent on their round trip? 
Class 4 Maths - Multiplication - Question AnswersSol: 

  • S as the number of students (45 students),
  • T as the number of teachers (6 teachers),
  • Cas the cost per student ticket (Rs. 175),
  • Ct as the cost per teacher ticket (Rs. 275).

The total cost for students (Ts) is given by the formula: Ts=S×Cs

And the total cost for teachers (Tt) is given by the formula: Tt=T×Ct

We can find the total cost (Ttotal) by adding the total cost for students and the total cost for teachers: Ttotal=  Ts+Tt

Substitute the given values into the formulas:  Ts = 45 × 175
Class 4 Maths - Multiplication - Question Answers

and Tt = 6×275
Class 4 Maths - Multiplication - Question Answers

Ttotal = T+ T= 7875 + 1650 = 9525

18 → 20 (Rounding off to ten's place).
325 X 18 → 300 X 20 = 6,000.
Thus, estimated product is 6,000.
