Questions & Answers about अगर तुम सच बोलोगी, तो मैं खुश रहूँगी।
That is normal in Hindi.
In Hindi, a future condition often uses the future tense in both parts:
- अगर तुम सच बोलोगी = if you tell / if you will tell the truth
- तो मैं खुश रहूँगी = then I will be happy
So the Hindi structure is more literally like If you will speak the truth, then I will stay happy, but the natural English translation is If you tell the truth, I’ll be happy.
They work like if ... then ...
- अगर = if
- तो = then
So:
- अगर तुम सच बोलोगी, तो मैं खुश रहूँगी। = If you tell the truth, then I will be happy.
In everyday Hindi, तो is often optional:
- अगर तुम सच बोलोगी, मैं खुश रहूँगी।
You may also hear the condition expressed without अगर, especially in speech:
- तुम सच बोलोगी तो मैं खुश रहूँगी।
But for learners, अगर ... तो ... is a very clear pattern.
