Question
In a code language, 'MAGNESIUM' is written as '55' and
'NITROGEN' is written as '48'. How will 'COPPER' be written in that language?Solution
The logic followed here is: From the left end, the sum of the place values (as per English alphabetical series) of all the letters, which are at even position is the coded number. MAGNESIUM = (1 + 14 + 19 + 21) = 55 NITROGEN = (9 + 18 + 7 + 14) = 48 COPPER = (15 + 16 + 18) = 49
390.11 ÷ 12.98 × 5.14 – 119.9 = √?
(2100.23 ÷ 34.98) + (864.32 ÷ 23.9) + 1854.11 =?
[(5/6 of 719.81) + 30% of 499.79] × (√99.89 + 25% of 399.69) = ?
What approximate value will come in place of question (?) in the following given expression? You are not expected to calculate the exact value.
...139.88% of 119.89 + 1451.89 ÷ 6.01 - √196.01 = ? ÷ 3.01 + 215.98
[(120.96 × 12.09) ÷ ?] ÷ 6 = 19.96% of 55.07
766/51 ÷ 387/42 × 121/13 = ?
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
(15.99)2 + 219.98% of 20.01 = ?2 × 75.01%
