120 more marks

80/100x750=600

600-480=120

Answer 2

120 more marks more is needed to secure 80 %

Solution:

Given that,

Jagdish got 64% marks out of 750

We need to find the marks needed more to secure 80%

From given,

80 % - 64 % = 16 %

Thus, 16 % marks of 750 is needed more to secure 80 %

Find 16 % of 750

$\rightarrow 16 \% \times 750\\\\\rightarrow \frac{16}{100} \times 750\\\\\rightarrow 0.16 \times 750\\\\\rightarrow 120$

Thus 120 more marks more is needed to secure 80 %
