fgiga [73]

Answer:

Lebeled Price of watch = Rs. 2000

Selling price pf the watch = Rs. 1600

Step-by-step explanation:

  • ∴ S = L - 20% L
  • ∴ S = 0.8 L   ..... (1)
  • ∴ S = P + (1/3)P
  • ∴ S = (4/3) P  ..... (2)
  • As we know, P = 1200
  • ∴ S  (4/3) × 1200
  • ∴ S = Rs. 1600
  • 1600 = 0.8L
  • ∴ L = 1600 ÷ 0.8
  • ∴ L = Rs.2000
  • ∴ Lebeled Price of watch = Rs. 2000
  • Selling price pf the watch = Rs. 1600

Kaveri has a total rs 590 as currency notes is the denominations ofrs50 , rs 20 , and rs 10 . the ratio of the number of rs 50 n
DerKrebs [107]
Let
x = number of rs 50
y = number of rs 20
z = number of rs 10

Because there are 25 total notes,
x + y +  z = 25              (1)

The ratio of rs 50 to rs 20 is 3:5, therefore
x = 0.6y                       (2)

The total amount is rs 590, therefore
50x + 20y + 10z = 590      
or
5x + 2y + z = 59            (3)

Subtract (1) from (3).
4x + y = 34            (4)
Substitute (2) into (4).
4*(0.6y) + y = 34
3.4y = 34
y = 10

From (2), obtain
x = 6
From (1), obtain
z = 25 - 6 - 10 = 9

Answer:
Kaveri has
 6 rs 50 notes,
10 rs 20 notes,
 9 rs 10 notes.
