Alok starts walking from P with speed of 6 km/h towards Q. Raman starts at same time from P towards Q with speed of 9 km/h. Raman reaches Q, turns back and starts walking towards P. He meets Alok at R. If PQ is 15 km, then what is PR?
आलोक P बिंदु से Q की ओर 6 km/h की गति से चलना शुरू करता है। रमन 9 km/h की गति के साथ P से की Q की ओर चलना आरम्भ करता है। रमन Q पर पहुँचता है, वापस मुड़ता है और P की ओर चलना शुरू कर देता है। वह आलोक से R पर मिलता है। यदि PQ 15 km है, तो PR कितना है?
