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 Β 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 Γ 6.4 + 4.8 Γ 10) Γ 120/100= 6.72(a + 10) =>6.4a Γ 120/100 + 48 Γ 120/100= 6.72a + 67.2 =>0.96a= 9.6 Β a= 9.6/0.96= 10kg.
139 + 323 β β169 + ? = 450
Determine the simplified value of the given mathematical expression.
Simplify the following expression:
Β Β (525 +175) Β² - (525 β 175) Β² / (525 Γ 175)

What will come in the place of question mark (?) in the given expression?
(63 - ?) Γ· 5 + β625 = 19 X (9 - 6)
What value should come in place of (?) question mark.
[36% of 250 + (3/5 of 320) β 18] Γ· 6 = ?
Evaluate: (936 Γ· 12) Γ (225 Γ· 15) β (144 Γ· 12) Γ 18
