Question
One dose and two idly cost Rs.14.
Three dose and one idly cost Rs.17.
What is the cost of 5 dose and 5 idly cost? (in Rs)
a. 50
b. 40
c. 55
d. 45
Solution
Let's solve this problem step by step.
Let's assume the cost of one dose is x and the cost of one idly is y.
From the first statement, "One dose and two idly cost Rs.14", we can form the equation:
x + 2y = 14 ---- (1)
From the second statement, "Three dose and one idly cost Rs.17", we can form the equation:
3x + y = 17 ---- (2)
Now, we have two equations and two variables. We can solve these equations to find the values of x and y.
Let's multiply the first equation by 3 and the second
