Question

in an examination piyush scored 490 marks . if he scored 70℅ marks , find the maximum marks.

Answer 1

hello here is your answer ✓✓

marks scored by Piyush=490
his scores=70% marks out of 100%
so marks decreased =100%-70%=30%
let the maximum marks be =x

A/q

x - 30% of x =490
$x - \frac{30}{100} x = 490 \\ \\ x - \frac{3}{10} x = 490 \\ \\ \frac{10x - 3x}{10} =490 \\ \\ \frac{7x}{10} = 490 \\ \\ 7x = 490 \times 10 \\ \\ x = \frac{4900}{7 } \\ \\ x = 700$
so the maximum marks = 700
