Best answer
Correct Answer - Option 3 : 400

Given:

There are an equal number of 25 Paisa coins, 50 Paisa coins and 1 Rupee coins. 

Formula used:

Total amount = Value of each coin × Number of coins

Calculation 

  Let the number of each type of coins = x

 We are doing whole calculation in terms of paisa. 

⇒ 25x + 50x + 100x = 70000                 (as 1 rupee = 100 paisa)

⇒ 175x = 70000

​⇒ x = 70000/175

⇒ x = 400

⇒ Number of each type of coins =  400

∴ Number of coins of each type are 400.
