Question
The ratio of present ages of Sneha to that of Akash is 6:8
while the ratio of present ages of Vikram to that of Akash is 5:8. If the age of Vikram, 3 years ago from now was 27 years, then find the sum of present ages of Sneha and Akash.Solution
ATQ,
Let the present age of Sneha and Akash be '6x' years and '8x' years, respectively.
So, present age of Vikram = 5/8 × 8x = 5x years
Vikram's present age = (27 + 3) = 30 years.
So, 5x = 30
Or, x = 6
Required sum = (6x + 8x) = (14x) = (14 × 6) = 84 years
What will come in the place of question mark (?) in the given expression?
(63 - ?) ÷ 5 + √625 = 19 X (9 - 6)
- What will come in place of (?), in the given expression.
(4² + 6²) × 2 = ? What will come in the place of question mark (?) in the given expression?
(40/25) X 80 - ? = 45% of 300 - 5525.6% of 250 + √? = 119
1220 ÷ 61 ÷ 5 + 450 of 20% - 70 = √ ?
Simplify the expression:
(5x + 15) / (x² + 3x)
What will come in the place of question mark (?) in the given expression?Â
435 ÷ 29 X 792 ÷ 44 = √(? + 14) + 35 + 221 ÷ 17
...192.251 + 326.233 + 125.021 + 19.273 = ?
36% of 640 – 12.5% of 352 + 25% of 640 = ? – 48% of 432
Simplify the following expressions and choose the correct option.
18 * 15 - {3/5 of 250 + 72}
