Let the no. of Hindi speakers be x.

The ratio of Hindi speakers to Tamil speakers is 1 ? 2.

Total no. of Tamil speakers is less than English speakers by 780 and 70% of the total employees can speak English.

So, No. of Tamil speakers = ((70/100) × 1500) - 780 = 270

According to the question,

Hindi ? Tamil = 1 : 2

⇒ 1/2 = x/270

⇒ x = 270/2 = 135

Thus, No. of Hindi speakers = 135

The non-English speakers contain 10% Tamil speakers who can also speak Hindi.

No. of Tamil Speakers who can speak Hindi

= 10% of (30% of total employees) = 10% of (30/100 × 1500) = 10/100 × 450 = 45

∴ Percentage of Hindi speakers that can speak Tamil = 45/135 × 100 = 33.33%
