Question

LJ kgs of rice for 1200. Rahim sells 75 kgs
the ratios in proportion ?
portion = 18
ution :
hod-1 Ratio of weights of rice
25 : 75 = 1:3
Ratio of cost of rice
1200 : 3600 = 12 : 36 = 1
Both ratios are equal, so given ratios are in proportion.
od-2 Here two ratios are 25 : 75 and 1200 : 3600
Product of extremes
25 X 3600 90,000
Product of means
75 x 1200 90,000
Since product of extremes = product of means,
25, 75, 1200, 3600 are in
Exercise - 6.2
heck whether the following are in proportion ? or not?
) 10, 12, 15, 18
(b) 11, 16, 16, 21
8, 13, 17, 19
(d) 30, 24, 20, 16
ite true or false for each of the following
4: 2 :: 14:7
(b) 21 : 7 :: 15:5
13 : 12 :: 12 : 13
(d) 5:6:: 7:8​

Answer:

option d

Step-by-step explanation:

LJ kgs of rice for 1200. Rahim sells 75 kgs

the ratios in proportion ?

portion = 18

ution :

hod-1 Ratio of weights of rice

25 : 75 = 1:3

Ratio of cost of rice

1200 : 3600 = 12 : 36 = 1

Both ratios are equal, so given ratios are in proportion.

od-2 Here two ratios are 25 : 75 and 1200 : 3600

Product of extremes

25 X 3600 90,000

Product of means

75 x 1200 90,000

Since product of extremes = product of means,

25, 75, 1200, 3600 are in
