Question

19. A certain quantity of Basmati rice is divided into two parts in the ratio 4 : 7. If the second part of rice is 98 kg, findi
(i) the weight of the first part of rice
(ii) the total quantity of rice
20.If the bus fare in a certain route for 38 km is * 494, what will be the fare for 12 km?​

Answer 1

Answer:

19) (i) 4:7 = x:98

now do product of extreams = product of means

7 × x = 98 × 4

7x = 392

x= 392 / 7

x = 56

therefore, first part is 56.

(ii) first part = 98

second part = 56

total = 98 +56

= 154

20) 38 : 494 = 12 : x

now do product of extremes = product of means

38x = 494 x 12

38x = 5928

x = 5928/38

x = 156

therefore, the fare route of 12 km = 156
