let the number of rupees 50 notes on rupees $20 notes
three x and y axis respectively but she have 25 notes in total
therefore the number of rupees equals to 25 - 3 x + 5 x equals to 25 - 8 x
the amount she has.
from rupees 50 notes is 23 x into 50 is equal to rupees 150 x
from rupees 20 notes is 5x into 20 into rupees 100 x
from rupees 10 notes is 25 - 8 x into 10 is equal to rupees 250 - 80 x
money she has equal to 150 X + 100 x + 15 - 8 x equals to rupees 178 + 120 but she has rupees 590
therefore 176 + 250 is equal to 594 170 x is equal to 5 90 - 256 348 901 2nd 234 2017 equal to 2
the number of rupees 50 notes she has equal to 3 x is equal to 3 into 2 equal to 6
the number of rupees 20 notes she has quiz 25 X equal to 5 into 2 equal to 10 the number of rupees 10 note she has equal to 25 - 8 x 8 X equal to 25 - 82 = 25 - 16 is equal to 9
Let 50 Rs note be 3x
20 Rs note will be 5x
10 Rs note willbe(25-8x)
Total denomination=590
According to question
50(3x)+20(5x)+10(25-8x)=590
