Answer 1

Answer:

Given, Sonakshi had 1000₹ currency in the form of 50 , 100 ₹ denominations

50 ₹denominations are thrice of 100₹ ...

• By the problem ;
• 100x+3(50x) =1000
• 100x+150x =1000
• 250x =1000
• x =1000/250
• x =4

if x=4 then,100 x =100×4 =400

if x=4 then, 50x =50×4 =200

$3(50x) = 3(200) = 600$

400+600=1000

• Dominations of 50₹ = 600/50 = 12 notes
• Dominations of 100₹ =400/100 = 4 notes.....
