Q:

A) I and II | B) I and III |

C) Only III | D) I and either II or III |

Answer:

Explanation:

Explanation:

From I and II,

Length = 3x = 48 m

∴ x = 16

Breath = 2x = 32 m

Hence, Area of floor = 48 × 32

Cost of flooring = 48 × 32 × 850 = ₹ 1305600

From I and III, 2(l +b) = 160

2(3x + 2x) = 160

10x = 160

∴ x = 16

∴ Length = 3 × 16 = 48 m

Breadth = 2x = 32m

Cost of flooring = (48 × 32) × 850 = ₹ 1305600

Similarly, from II and III, we can find

l = 48 m

b = 32 m

and Total cost of flooring = ₹ 1305600
