  • 1028
  • 1056
  • 1043
  • 1142
  • 1145
  • Explanation:

    Number of students in Institute P after increased by 15% = 340×115/100 = 391

    Number of students in Institute Q after increased by 22% = 300×122/100 = 366

    Number of Students in Institute R after increased by 10% = 260 × 110/100 = 286

    ∴ Total number of students in all three institutes = 391+366+286 = 1043
