Question

Sum of ₹1000 is in the form of denominations of ₹10 and₹50. If the the total number of notes is 60, find the number of notes of each type

Answer 1

Answer:

50, 10 respectively

Step-by-step explanation:

10 of 50 rupees

50 of 10 rupees

suppose

x is number of 50 rupees

then

60-x is number of 10 rupees

now from questions -

x × 50 rupees + (60-x) × 10 rupees = 1000 rupees

so,

50x + (60-x) × 10 =1000

50x + 60×10 - x×10 =1000

50x-10x = 1000-600

40x = 400

x =400/40=10

so number of 50 rupees = 10

&

number of 10 rupees = 60-10 =50
