Answer 2

Required numbers of balls are Six .

Step-by-step explanation:

$\mathcal{\small{\red{\underline{\underline{Correct Question }}}}}$

15 iron balls of the same size weigh 10kg 50g. How many of them will weigh 4 kg 20g ?

$\mathcal{\small{\red{\underline{\underline{Solution }}}}}$

Total weight of 15 balls : 10kg50g

: 1050 gm

Weight Of one ball : 1050 / 15

= 70 gm

Now ,

We have to find the total number of ball whose combined weight is 4kg20g that is 420 g

So total number of balls = Total weight of balls / Weight of one ball .

= 420 / 70

= 6

So required numbers of balls are 6.
