Question

Answer 1

Answer:

third number=100

second number=150

first number=120

then 150÷120×100= 125%

Answer 2

$\underline{ \sf{ \underline{☃Given: }}}$

• Two numbers are respectively 20% and 50% more than a third number.

$\underline{ \sf{ \underline{☃Find:}}}$

• What percent is second of the first?

$\sf \underline{ \underline{☃Solution:}}$

$\sf{Let \: take \: third \: number \: as \: x}$

$\sf{Then \: the \: first \: number \: will \: be \: 20 \: of \: x}$

$\sf{First \: number = 20x}$

$\sf{Then \: the \: second \: number \: will \: be \: 50 \: of \: x}$

$\sf{Second \: number = 50x}$

Percentage of second of the first number:-

$\to \sf{ \frac{20x}{50x} \times 100 }$

$\to \sf{ \frac{20}{50} \times 100 }$

$\to \sf{20 \times 2 = 40\%}$

${ \therefore{ \sf {percent \: of \: second \: of \: the \: first \: number \: is \: 40\%}}}$
