Question
Ram has Rs. 1000 in denomination of Rs. 2, Rs. 5 and Rs. 10
only. If the ratio of number of coins of Rs. 2, Rs. 5 and Rs. 10 is 5:3:10 respectively. Find the total number of coins.Solution
Let the number of coins of Rs. 2, Rs. 5 and Rs. 10 be 5x, 3x and 10x respectively.
ATQ,
Or, (5x X 2 + 3x X 5 + 10 X 10x) = 1000
Or, 125x = 1000
So, 'x' = 8
Therefore, required number of coins = (5x + 3x + 10x) = 18 x 8 = 144
5.5 × 3.2 × 2.3 = ?
What value will come in place of (?) question mark in the given expression.
17 × 15 – 48 ÷ 4 + 9² = ?
Find the value of.
( ∛ ∛ 343 )3 × ( ∛ ∛216 )3
(3984 ÷ 24) x (5862 ÷ 40) = ?
5555 ÷ 11 ÷ 5 = 100 + ?
18 * 9 + 25% of 120 + 50% of 200 = ?
Simplify the following expressions and choose the correct option.
18² + (27 ÷ 3) × 11 − 250 = ?
What will come in the place of question mark (?) in the given expression?
(20% of 820 – 56 + 11 × 8) 1/2 = ? – 62
Simplify the following expressions and choose the correct option.
√2116 + 152 ÷ 9 - 33
