Deputy Prime Minister Kanat Bozumbaev disclosed the figures while meeting Azerbaijani officials, the Russian news agency Interfax reported.
Flight J2-8243 was on the way from the Azerbaijani capital of Baku to the Russian city of Grozny in the North Caucasus on Wednesday when it was diverted and attempted an emergency landing 3km from Aktau, Azerbaijan Airlines said.

Azerbaijani President Ilham Aliyev said it was too soon to speculate on the reasons behind the crash, but said the weather had forced the plane to change from its planned course.
"The information provided to me is that the plane changed its course between Baku and Grozny due to worsening weather conditions and headed to Aktau airport, where it crashed upon landing," he told reporters.
Russia's civil aviation authority, Rosaviatsia, said preliminary information showed the pilots diverted to Aktau after a bird strike led to an emergency on board.
According to Kazakh officials, those aboard the Embraer 190 included 42 Azerbaijani citizens, 16 Russian nationals, six Kazakhs and three Kyrgyzstan nationals.
Azerbaijan's prosecutor-general's office previously said 32 of the 67 people on board had survived the crash, but told journalists the number was not final.
Mobile phone video circulating online appeared to show the aircraft making a steep descent before smashing into the ground in a fireball.
Flight-tracking data from FlightRadar24.com showed the aircraft making what appeared to be a figure eight once nearing the airport in Aktau, its altitude moving up and down substantially during the last minutes of the flight before hitting the ground.
FlightRadar24 separately said the aircraft had faced "strong GPS jamming", which "made the aircraft transmit bad ADS-B data", referring to the information that allows flight-tracking websites to follow planes in flight.

Russia has been blamed in the past for jamming GPS transmissions in the wider region.
Azerbaijan Airlines said it would keep members of the public updated and changed its social media banners to solid black.
It also said it would suspend flights between Baku and Grozny, as well as between Baku and the city of Makhachkala in Russia's North Caucasus, until its investigation into the crash has been concluded.
Aliyev, who was travelling to Russia, returned to Azerbaijan on hearing news of the crash, the president's press service said.
He was due to attend an informal meeting of leaders of the Commonwealth of Independent States, a bloc of former Soviet countries founded after the collapse of the Soviet Union, in St Petersburg.
Aliyev expressed his condolences to the families of the victims "and wish a speedy recovery to those injured".
He also signed a decree declaring December 26 a day of mourning in Azerbaijan.
Russian President Vladimir Putin spoke to Aliyev on the phone and expressed his condolences, the Kremlin said.
