`0.5 g` mixture of `K_(2)Cr_(2)O_(7)` and `KMnO_(4)` was treated with excess of `KI` in acidic medium. Iodine liberated required `100 cm^(3)` of `0.15N` sodium thiosulphate solution for titration. Find the per cent amount of each in the mixture.

Explanation

To solve the problem step by step, we will follow these calculations:

### Step 1: Define Variables
Let:
- \( a \) = mass of \( K_2Cr_2O_7 \) in grams
- \( 0.5 - a \) = mass of \( KMnO_4 \) in grams

### Step 2: Calculate Equivalent Masses
