Question
A piggy bank contains ₹10, ₹5 and ₹2 coins in the
ratio 3:4:6. If the total amount in the piggy bank is ₹620, how many ₹2 coins are there?Solution
ATQ,
Let the number of ₹10, ₹5 and ₹2 coins be 3x, 4x and 6x respectively.
ATQ:
(3x × 10) + (4x × 5) + (6x × 2) = 620
Or, 30x + 20x + 12x = 620
Or, 62x = 620
Or, x = 620 / 62 = 10
So, number of ₹2 coins = 6x = 6 × 10 = 60
What approximate value will replace the question mark (?) in the following?
? = 1...
16(17/23) + 11(15/46) - 15(17/25) =? - 19(13/23)
Find the approximate value of Question mark(?). No need to find the exact value.
(575.86 ÷ 24.03) × (35.96 ÷ 6.03) + √(255.76) = ?
...5983.987 + 59832.999 – 598.873 = ?
What approximate value will come in place of question (?) in the following given expression? You are not expected to calculate the exact value.
...(?)2 + 4.113 = 25.92 – 32.03
119.922% of 599.90 + (34.78/20.89) × √64.29 × 29.76 ÷ √24.92 = ?2 - 99.92
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exactvalue.)
35.11% of 159.99 + √195.97 ÷ 7.02 = ?
( 1000)1/3 × 10.11 × 4.97 ÷ 10.32 =? – 15.022
