Question
If it is possible to make a meaningful word using, 1st,
6th, 7th, 8th and 9th letters of the word ‘DISTURBANCE’, then what is the 2nd letter from the left side of the word formed? If no such word is formed then mark your answer as ‘X’. If more than two such words are formed then mark your answer as ‘Z’.Solution
1 st , 6 th, 7 th , 8th & 9th letters of word are D, R, B, A and N.
So, 1 meaningful words can be formed i.e., BRAND.
So, the 2nd letter from the left is R.
If (7a + b) : (7a - b) = 7:3, then find the value of a:b?
522 + 160% of 80 - 130 = ? X 13
140% of 75 + 152 - 160 = ?
25% of 240 + √? = (2/3) × 120
961 × 4 ÷ 31 – 15% of 180 = ? – 73
Calculate the simplified value of the given expression:

What will come in the place of question mark (?) in the given expression?
√1936 + (84 ÷ 2 × 1.5) – 35² + 18² = ?
8(3/4) + 5(1/6) – 4(3/4) = ?
{(80% of 650 + 25 × 12) – 20 × ?} = 760
36×?² + (25% of 208 +13) = 60% of 2400 + 17×18
