1. नन्हा-मुन्ना राही सबसे क्या बोलने के लिए कह रहा है?​

Answer»

Explanation:

Total PARTS of Alloy = 13+7+5 => 25

% of Copper 13 =

25 x 100 = 13 x 4 = 52%

% of Zinc =

7 25 x 100 = 7 x 4 = 28%

% of NICKEL =

5 25 x 100 = 5 x 4 = 20%

Therefore, the total percent adds up to 100%.

So,

% of Copper = 52%

% of Zinc = 28%

% of Nickel = 20%
