Answer:
(c) The given ratios are in proportion.
(d) The given ratios are NOT in proportion.
(e) The given ratios are NOT in proportion.
(f) The given ratios are NOT in proportion.
Step-by-step explanation:
(c) 150kg to 100kg and 135ml to 90ml
Product of the means = 100kgx135ml = 13500kg-ml
Product of the extremes = 150kgx90ml = 13500kg-ml
Since, Product of the means = Product of the extremes, the given ratios are in proportion.
(d) 15cm to 12cm and ₹90 to ₹200
Product of the means = 12cmx₹90 = 1080cm₹
Product of the extremes = 15cmx₹200 = 3000cm₹
Since, Product of the means ≠ Product of the extremes, the given ratios are NOT in proportion.
(e) 450gm to 2kg and 90hr to 240min
= 450gm to 2000gm and 5400min to 240min
Product of the means = 2000gmx5400min = 10800000gm-min
Product of the extremes = 450gmx240min = 108000gm-min
Since, Product of the means ≠ Product of the extremes, the given ratios are NOT in proportion.
(f) ₹40 to ₹48 and 24m to 18m
Product of the means = ₹48x24m = 1152₹m
Product of the extremes = ₹40x18m = 720₹m
Since, Product of the means ≠ Product of the extremes, the given ratios are NOT in proportion.
