Answer: 600
Explanation To find the number, you can set up an equation: 7% of x = 42 To solve for x, you can convert the percentage to a decimal by dividing by 100: 0.07x = 42 Then, divide both sides by 0.07: x = 42 / 0.07 x = 600 So, the number whose 7% is 42 is 600 !
Answer: x = 2y
Explanation Given: x / 4 = y / 2 Multiply both sides by 4: x = 2y
Answer: 4
Explanation 4+4-4x 4/4 =? =4+4- 4x1 =4+ 4-4 =4+ 0 =4
Answer: 12 years
Explanation Let A's current age be x and B's current age be y. Since A is twice as old as B, x = 2y. Three years ago, A's age was x - 3 and B's age was y - 3. Since A was three times as old as B, x - 3 = 3(y - 3). Solving the equations, we get x = 12. So, the correct answer is 12 years .
Answer: 16
Explanation The average is the sum divided by the number of quantities: Average = Sum / n 115 = 1840 / n To find 'n', multiply both sides by 'n' and then divide by 115: n = 1840 / 115 n = 16
Answer: 8%
Explanation Passed English = 80% Passed Math = 85% Passed both = 73% Passed at least one = 80% + 85% - 73% = 92% Failed both = 100% - 92% = 8% Last verified on 20-01-2026
Answer: 14
Explanation x = 7 — 4√3, we are required to find x + 1/x. 1/x = 1/(7 — 4√3) Rationalising 1/x, 1/x = {1/(7 —4√3)} × {(7 + 4√3)/7 + 4√3)} = {(7 + 4√3)}/{7² — 4²(√3)²} = (7 + 4√3)/(49 — 48) = 7 + 4√3. Therefore x + 1/x = 7 — 4√3 + 7 + 4√3 = 14 .
Answer: a= 5 Rs and b 200 Rs
