2. Nickel 3. Chromite 4. Dolomite 5. Kyanite 6. Mica Which of the above minerals are Non-metallic?Solution
Non-metallic minerals are minerals that do not contain any metals. Some examples of non-metallic minerals are limestone, mica, gypsum, coal, dolomite, phosphate, salt, and granite.
30% of 600 –
24% of 15% of 500 + 122 = ?2 – (232 ÷ 2)
√11025 x √5625 - (50)² = (?) + (73)²

What will come in the place of question mark (?) in the given expression?
34 X 11 - ? + 36 = 3 X 75 + 125
55% of ? = 45 + 20 × 6
135÷ 15 x 19 + 14807 = ? + √3249 - √9604
60 % of 640 - 57 × 2 - 1520 / 38 = ?
135.37 – 50.24 + 629.09 – 199.50 = ? – 214.68 + 42.65
28 × 3.5 +25 × 3.2 = ? - 62
