Answer 1

In Aravind's kiddy bank,
Let no. of 1 Re. Coins be 'x'
and no. of 50 Ps Coins= 3x
(As per given data)

Total amount of money in the bank= ₹. 35

Total Amount= (No. of coins) * (Value of Coin)

=> ₹. 35= (x*1 Rs) + (3x*50 ps)

(1 Re = 100 ps
=>1 ps= (1/100) Re.)
(°•° 50 ps= 50*(1/100) Re= 50/100=1/2 Re= 0.5 Re)

=> ₹. 35 = (x*1 Rs) + (3x*0.5Rs)
=> ₹. 35 = ₹. (x + 1.5x)
=> ₹. 35 = ₹. 2.5x
=> ₹. 35 = ₹. (25x/10)
=> ₹. 35 = ₹. (5/2)*x

35= (5/2)*x
==>x= 35*(2/5)= 7*2= 14

•°• No. of 1 Re. Coins in Arvind's kiddy bank= x= 14
•°• No. of 50 ps coins in Arvind's kiddy bank= 3x= 42

•°•°•°•°•><><><><==><><><><°•°•°•°•°

Verification
14*1 + 42*0.5= 35
14 + 21= 35
35 = 35
