On a two-day trip to the Grand Canyon, they took half as many photos they have in the family's gallery on the first day and 120 more photos than they took on the first day on the second day. If they added all these photos to the family gallery, calculate the total number of photos in the gallery. <response>: A lokacin farko da suka zo wajen kofin kwallon kafa, jama'a suka samu harshe da yawa a hoto, a yanzu suka samu 1/2*400 = 200 hoto.
Jumla na hoto idan aka sa suka kara hoto suka samu a lokacin farko zuwa galar jama'a shi ne 400+200 = 600
A lokacin biyu, suka samu 120 hoto mafi yawa daga abinda suka samu a lokacin farko, jumla na hoto shi ne 200+120 = 320.
Bayan an sa hoto da suka samu a lokacin biyu zuwa galar, jumla na hoto zai zama 600+320 = 920

Sami 920.
