Question

find the whole quantity if 30%of it is 580km

Answer 1

Let the whole quantity be x

A/Q,
$30\% \: of \: x = 580 \\ = > \frac{30}{100} \times x = 580 \\ = > x = \frac{580 \times 100}{30} \\ = > x = \frac{5800}{3} \\ = > x = 1933.33$

Therefore, the whole quantity is 1933.33 km

Answer 2

30 % is 580
30 / 100 × 580
30 / 10 × 58
= 3 × 58
= 174
now 70% of 174
70 / 100 × 174
7 / 10 × 174
7 × 17.4
= 121.8 + 174
= 195.8
