Question
How many kilograms of wheat, priced at Rs 6.4/kg, should
be mixed with 10 kg of gram flour priced at Rs 4.8/kg, such that by selling the mixture at a 20% profit, the selling price is Rs. 1.12 more than the average cost price per kg of both varieties of the mixture?Solution
ATQ, we can say that Let the quantity of Rs 6.4/kg be a kg. S.P of mixture= Rs [1.12 + (6.4 + 4.8)/2]=1.12 + 5.6= Rs 6.72 According to question, =>(a × 6.4 + 4.8 × 10) × 120/100= 6.72(a + 10) =>6.4a × 120/100 + 48 × 120/100= 6.72a + 67.2 =>0.96a= 9.6 a= 9.6/0.96= 10kg.
139 + 323 – √169 + ? = 450
Determine the simplified value of the given mathematical expression.
Simplify the following expression:
(525 +175) ² - (525 – 175) ² / (525 × 175)
420 ÷ 7 + 140 % of 20 + ? × 13 = 18 × 15
The valueof2 of5– 1/2 −[4÷2– 1/3 −{3/4−(5– 1/2 – 3/4 )}]is :
What will come in the place of question mark (?) in the given expression?
(63 - ?) ÷ 5 + √625 = 19 X (9 - 6)
What value should come in place of (?) question mark.
[36% of 250 + (3/5 of 320) − 18] ÷ 6 = ?
Evaluate: (936 ÷ 12) × (225 ÷ 15) − (144 ÷ 12) × 18
