Question

Meena went to a bank to withdraw Rs 2000. She asked the cashier to give her Rs 50 and Rs 100 notes only. Meena got 25 notes in all. Represent this situation algebraically.​

Answer 1

Step-by-step explanation:

let's use alligation method ,

ratio of 100 : 50 = 2:1

if only 50 rs note of 2000 = 2000/50 = 40 notes

if only 100rs note of 2000 = 2000/100 = 20 notes

(1) (2)

20 40

- -

25

= =

15 5

100rs note = 15 notes = 1500=1 part as ratio

50 rs note = 5 notes *2 = 10 notes = 500 = 2 parts
