A number is 30 more than its two-three .What is the number
A). 60
B). 30
C). 90
D). 120
Let the number be 'x'
Given, x is 30 more than its two three,
That is,
x = 30+2/3(x)
3x = 90+2x
3x-2x = 90,
x = 90
Therefore, the number is '90'.
2. If 51.97 - (81.18 - x) - 59.39 = 5.628, then value of x will be?
3. What will come in place of question mark (?) in the following question? 35 × 35 ÷ 70 + 16 × 50 = ?
6. The least number, that must be added to 1720 so as to obtain a perfect cube, is
7. [(523 + 27) * (187 - 35) / (424 + 16)] / [110/22 of (2 * 38)] = ?
9. The number, whose square is equal to the difference of the squares of the numbers 68 and 32, is
