Answer:
The cost of 1 note book = Rs 43.5
Step-by-step explanation:
Given in question as :
95 pens (P) + 89 notebook (N) total cost = Rs 7434
1 pen (P) + 1 (N) total cost = Rs 81
So, from above equation
95 pens (P) + 89 notebook (N) total cost = Rs 7434
1 × 95 pen (P) + 1× 95 notebook (N) total cost = Rs 81 × 95
Or, (95 pens (P) + 95 notebook (N) ) - (95 pens (P) + 89 notebook (N) ) = (7695 - 7434)
Or , 6 N = Rs 261
Or, N = = Rs 43.5
Hence the cost of 1 notebook is Rs 43.5 Answer
