Amount of beta ray received in 1 min = 5 % of 3600 = 180 unit

Beta ray received in 10 minutes = 10 x 80 = 1800 unit

IR received in 1 minute = 10 % of 3600 = 360 unit

IR received in 3 minute = 3 x 360 = 1080 unit

So amount of beta rays to IR rays = 1800/ 1080

= 1.66

Amount of beta ray received in 1 min = 5 % of 3600 = 180 unit

Beta ray received in 10 minutes = 10 x 80 = 1800 unit

IR received in 1 minute = 10 % of 3600 = 360 unit

IR received in 3 minute = 3 x 360 = 1080 unit

So amount of beta rays to IR rays = 1800/ 1080

= 1.66
