Discussion

Explanation:

Let cost of a Roti, a plate of Tadka and a cup of tea be Rs. a, b and c respectively.

Hence, we have,

10a + 4b + c = 80, and                 … (I)
 
7a + 3b + c = 60                          … (II)

Now, by II – I,

3a + b = 20                                 … (III)

Hence, by, (I) – 3(III), we have,

a + b + c = 20

Hence, 5a + 5b + 5c = 100

Hence, Anthony will pay Rs. 100.

Hence, option (d).
