Question

the cost of 5 1 by 4 kg of mangoes is rupees 186 at what rate per kg are the mangoes being sold

Answer 1

Given
Cost of 21/4 kg of mangoes = Rs 186
Therefore
Cost of 1 kg of mangoes = 186 ÷ (21/4)
                                          = 186*4/21
                                          = Rs 35.428 (nearly).
The mangoes were being sold at Rs 35.428 (nearly) per kg.

Hope this helps you.

Answer 2

Hi user !!

Here's your answer !!

Cost of 5 * 1 / 4  = Rs 186

To find cost for 1 kg of mangoes.

5 * 1 / 4  = 21 / 4 kg

Lets solve this using ratio and proportion method:

21 / 4 : 186 :: 1 : x  (Here x is meant as the cost for that amount of mangoes)

= 21 / 4 * x = 186

=> x = 186 * 4 / 21

=> x = 35.42

Hence cost of mangoes for 1 kg is Rs 35.42.

Hope my answer helped you !!

Have a great day :-)
