Let common multiple of ratio 5:4 be x.
=> No. of Rs. 100 notes = 5x
=> No. of Rs. 50 notes = 4x
Value of 5x Rs. 100 notes = 5x*100 = Rs. 500x
Value of 4x Rs. 50 notes = 4x*50 = Rs. 200x
As per question,
=> 500x+200x = 7000
=> 700x = 7000
=> x = 10
∴ No. of Rs. 100 notes = 5(10) = 50
∴ No. of Rs. 50 notes = 4(10) = 40
=> No. of Rs. 100 notes = 5x
=> No. of Rs. 50 notes = 4x
Value of 5x Rs. 100 notes = 5x*100 = Rs. 500x
Value of 4x Rs. 50 notes = 4x*50 = Rs. 200x
As per question,
=> 500x+200x = 7000
=> 700x = 7000
=> x = 10
∴ No. of Rs. 100 notes = 5(10) = 50
∴ No. of Rs. 50 notes = 4(10) = 40

Answer:
Fifty ₹100 notes and forty ₹50 notes
Step-by-step explanation:
Let number of ₹100 notes be 5y and number of ₹50 note be 4y.
Total money Rita has = ₹(5y×100+4y×50) = ₹500y+200y = ₹700y
700y=7000
y=7000÷700=10
So, number of ₹100 notes = 5×10 = 50 and number of ₹50 notes = 4×10 = 40
