Question

There are 14 red balls and 9 blue balls in a basket. The total weight of blue and red balls is 128.61g. A blue ball is 2.79g heavier than red ball. Find the weight of blue ball?
The answer is 7.29 g but can anyone send the solution​

Answer 1

Answer:

Let the red ball be x

blue ball = 2.79+x

So 14 red ball = 14x

So 9 blue ball =9x +25.11

So total weight =

25.11+9x+14x =128.61

25.11+23x =128.61

23x =128.61-25.11=

23x= 103.50=

X=4.5

So red ball weight = 4.5g

So blue ball = 4.5g+2.79g

Blue ball = 7.29. Answer
