Answer 1

Given :

• Total money saved = Rs.800
• Saved money in the ratio = 9:7

$\\ \rule{200pt}{3pt}$

To Find :

• Money saved by each = ?

$\\ \rule{200pt}{3pt}$

Solution :

⚝ ${\underline{\pmb{\frak{ Let \; the \; Ratios \; :- }}}}$

• ➟ Money saved by Rahul = 9y
• ➟ Money saved by Renuka = 7y

$\\ \qquad{\rule{150pt}{1pt}}$

⚝ ${\underline{\pmb{\frak{ Calculating \; the \; value \; of \; y \; :- }}}}$

${\longmapsto{\qquad{\sf{ 9y + 7y = 800 }}}} \\ \\ \\ \ {\longmapsto{\qquad{\sf{ 16y = 800 }}}} \\ \\ \\ \ {\longmapsto{\qquad{\sf{ y = \dfrac{800}{16} }}}} \\ \\ \\ \ {\longmapsto{\qquad{\sf{ y = \cancel\dfrac{800}{16} }}}} \\ \\ \\ \ {\qquad \; \; {\therefore \; {\underline{\boxed{\pmb{\red{\frak{ y = 50 }}}}}}}}$

$\\ \qquad{\rule{150pt}{1pt}}$

⚝ ${\underline{\pmb{\frak{ Calculating \; the \; Money \; Saved \; :- }}}}$

• ➳ Money Saved(Rahul) = 9y = 9(50) = ₹ 450

• ➳ Money Saved(Renuka) = 7y = 7(50) = ₹ 350

Answer 2

So c'mon let's answer this Question with peace full mind :)

Given :-

• Saved Money = ₹800
• Ratio = 9 :7

To Find :-

how much money did each of them save

Solution:-

• Rahul = 9a
• Renuka = 7a

➻9a + 7 = 800

➻16a = 800

➻ a = 800/16

➻a = 50

Money saved by Rahul = 9a

➻ 9×50

➻ ₹450

Money saved by Renuka = 7a

➻7×50

➻ ₹ 350
