Which of the following is most commonly used in fluorescent lamp?
Low pressurised mercury vapour and Argon gas is filled in fluorescent lamp.
116*2/3% of 18600 + 666*2/3% of 1290 = 457*1/7% of 1750 + 555*5/9% of 3150 + ?
18(1/3) + 9(2/3) – 10(1/3) = 1(2/3) + ?
44% of 560 + 68% of 2160 × 5/12 =? + 32% of 920.
5.5 × 3.2 × 2.3 = ?
280 – 70 × 14 ÷ 5 = ? – 21 of 3
3/7 Of 504 ÷ 12 + 17 = √?
10% of 80% of 50% of ? = 4
(64/25)?× (125/512)?-1= 5/8
20% of 10% of 900 + 84/12 = ?2
5(? + 2) = 3125
