Atif ordered 16 chapatis, 5 plates of rice, 7 plates of mixed vegetable and 6 ice-cream cups. The cost of each chapati is Rs.6, that of each plate of rice is Rs.45 and that of mixed vegetable is Rs.70. The amount that Atif paid the cashier was Rs.961. Find the cost of each ice-cream cup?
Correct answer: A. Rs.25
- A. Rs.25
- B. Rs.22.50
- C. Rs.20
- D. Rs.17.50
- E. None of these
Explanation
The known cost is 16 x Rs.6 + 5 x Rs.45 + 7 x Rs.70 = Rs.811. The six ice-cream cups therefore cost Rs.961 - Rs.811 = Rs.150, so each costs Rs.150 ÷ 6 = Rs.25. A likely mistake is option c, Rs.20, from subtracting or dividing the total incorrectly.

About Linear Equations
Linear equations contain variables only to the first power and produce straight-line relationships when represented graphically. Problems involve solving equations with brackets, fractions, and variables on both sides, forming equations from statements, and handling simultaneous linear equations, which differ from quadratic equations by having no squared variable.
