A shopkeeper, sold almonds at the rate Rs 1250 per kg and bears a loss of 7%. Now if he decides to sell it at Rs 1375 per kg, what will be the result?
Let the CP of almonds be x. Given that, on selling them at the rate Rs 1250 per kg shopkeeper bears a loss of 7%. ∴93% of x = 1250 ⇒x = 125000/93 ≈ Rs1344 Now if he decides to sell it at Rs 1375 per kg, profit =

Profit after selling a watch for Rs. 614 is the same as loss after it for Rs. 572. Find the cost price of the watch.
Let the cost price of the watch = x
A.T.Q.
614 - x = x - 572
2x =614+572 = 1186
x = 593
To make this perfect square, we will have to choose r=2, as the other term of n has power 1, wo we cannot take higher values of r.
Hence, our equation has now become,
n2 – tn + ¼ .... (eq1)
Now compararing it with
(n ± ½ )2
= (n2 ± 2. ½ . n + ¼)
= n2 ± n + ¼ ..... (eq2)
comparaing (eq1) and (eq2),
we get t= ±1
Raj and Prem walk in opposite direction at the rate of 3 km and 2 km per hour respectively. How far will they be from each other after 2 hrs?
Distance covered by Raj in 2 hour =2*3 = 6 km Distance covered by Prem in 2 hour =2*2 = 4km ∴ Distance between then after 2 hour =6+4 = 10km
A fraction, whose 4/7 part is when subtracted from itself and resultant is subtracted from 3/7 gives 1/14 is?
Let the required fraction is x. A/Q
A person buys spirit at Rs.60/liter and added some water to it and then sells it at Rs.75 per liter, what is the ratio of spirit to water if his profit in this deal is 37.5 %?
Let the total cost of the mixture is x
S.P = 75 Rs. With 37.5 % profit
⟹ 6: 60 = 1: 10 this is ratio of water to spirit
∴ Ratio of spirit to water will be 10: 1
If 4A = 6B = 5C then A : B : C is:
Let, 4A = 6B = 5C = x
Therefore, 4A = x
⇒ A = x/4
Similarly, B = x/6 and C = x/5
