6.Lekshmi is a cashier in a bank . she ha currency notes of denominations Rs 100,Rs 50,Rs 10 respectively.The ratio of the number of these notes is 2:3:5.The total cash with lakshmi is Rs 400000.How many notes of each denomination does she have? 7.I have total of Rs 300 in coins of denomination Rs1,2,5 resp.The number of Rs 2 coins is 3 times the number of Rs 5 coins.The total no of coins is 160.How many coins of each denomination are with me

Let the common ratio between the numbers of notes of different denominations be x. Therefore, numbers of Rs 100 notes, Rs 50 notes, and Rs 10 notes will be2x, 3x, and 5x respectively.

Amount of Rs 100 notes = Rs (100 × 2x) = Rs 200x

Amount of Rs 50 notes = Rs (50 × 3x)= Rs 150x

Amount of Rs 10 notes = Rs (10 × 5x) = Rs 50x

It is given that total amount is Rs 400000.

? 200x + 150x + 50x = 400000

? 400x = 400000

On dividing both sides by 400, we obtain

x = 1000

Number of Rs 100 notes = 2x = 2 × 1000 = 2000

Number of Rs 50 notes = 3x = 3 × 1000 = 3000

Number of Rs 10 notes = 5x = 5 × 1000 = 5000
