Answer: (3)

Solution: (3)

Total cost of wooden flooring

$= \text{₹} (23 \times 29+13 \times 17) \times 170$

$= \text{₹} (667+221) \times 170$

$= \text{₹} 150960$

Total cost of marble flooring

$= \text{₹} (14 \times 13+21 \times 13+29 \times 21 $) $\times 190$

$= \text{₹} (182+273+609) \times 190$

$= \text{₹} 202160$

$\therefore$ Required ratio $=150960: 202160$ $=1887: 2527$
