Galvanization involves coating iron or steel with zinc to prevent rusting. The process involves dipping the base metal into molten zinc, forming a protective barrier that not only shields the iron from moisture and oxygen but also provides sacrificial protection—the zinc corrodes first, thereby offering extended protection to the underlying metal.
16.98 × 88.05 + 1999.996% of 299.08 + 5.005 % of 4999.997 = ? × 20.98 × 40.009
If the difference between the compound interest (compounded annually) and the simple interest accrued over two years at a rate of...
(124.99)² = ?
81% of 1550 + 27² = ? + 1386 ÷ 22
(1011 × 4.465 + 1012 × 0.3535) ÷ (160 × 10⁵) = 10? ÷ 2
...What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exactvalue.)
(44.85% of 639.79 + 3/8 of 480.23) × (√63.84 – 19.99% of 499.71) = ?
599.9 - ? + 64.9 = (5% of 300.012) × 10.032
? * 6.97 = (300.04 ÷ 10.99) % of 4620 - 839.97
