Jill is putting a tile floor in her kitchen She needs 52 tiles to cover the whole floor. There are 24 tiles in a box. A box \( \operatorname{costs} R s .23 .95 . \) Individual tiles cost \( R s \) 2.95. Sales tax is \( 5 \% \). How much will 52 tiles cost approximately, including sales tax?
- A. \( R s .50 \)
- B. Rs. 57
- C. \( R s .60 \)
- D. \( R s .63 \)
Step-by-step solution
Buy 2 boxes (48 tiles) for Rs. 23.95 each = Rs. 47.90, and 4 individual tiles at Rs. 2.95 each = Rs. 11.80. Total before tax = Rs. 59.70. Add 5% sales tax: 59.70 × 0.05 = Rs. 2.985, total ≈ Rs. 62.685 ≈ Rs. 63.
