Question

7% of 400+? % of 66 = 30.5×2​

Answer 1

hey mate!

50 % is the correct answer.

Answer 2

${\huge {\mathfrak {Answer :-}}}$

➡️ Let it be 'x' %

So, 7/100 * 400 + x/100 * 66 = 30.5 * 2

Or, 28 + 66x/100 = 61

Or, 66x/100 = 33

Or, x = 100 * 33 / 66

Or, x = 100/2 = 50.

➡️ Hence, the answer is 50%.

That's it..
