Ranjana's mother gave her Rs 245 for buying new year cards. If she got some 10 rupee cards 2/3 as many 5 rupee cards and 1/5 as many 15 rupee cards, how many of each kind did she buy?

Given:- Total number of money Ranajana have = Rs 245

Now, Let, Number of Rs 10 cards bought = x

Therefore, Number of Rs 5 cards bought = x

Number of Rs 15 cards bought = x

So, Total money spent

⇒ x = 15 i.e 15, Rs 10 cards bought

Hence,

Number of Rs 10 cards = 15
