Question
‘Rina’ and ‘Meena’ invested Rs. 1,800 and Rs. 3,000
respectively in a startup. After 15 months, Rina increased her capital by 50% while Meena decreased hers by Rs. 600. If the total profit after 3 years is Rs. 5,400, what is the profit difference between them?Solution
ATQ,
Increased investment of ‘Rina’ = 1800 × 1.50 = Rs. 2,700
Decreased investment of ‘Meena’ = 3000 – 600 = Rs. 2,400
So, ratio of profit shares of ‘Rina’ and ‘Meena’ = (1800 × 15 + 2700 × 21):(3000 × 15 + 2400 × 21) = 13.5:16.2 = 15:18
Difference between profit shares = 5400 × {(18 – 15) ÷ (18 + 15)} = Rs. 600
[1.45 X 1.45 X 1.45 + 0.55 X 0.55 X 0.55 + 4.785] = ?
290 × 15 ÷ 5 + 34 + 50 = ?
What will come in the place of question mark (?) in the given expression?
(√? - 17) X 40 + 145 = 1000 - 15
(2/5)(32% of 4500 – 440) = ? × 8
Find the value of ‘x’ if (5 × 196 – 340 ÷ 17) ÷ 20 = √1600 – x.
((8)0- (0.1)-1)/( (6/16)-1 ×(3/2)3+ ((-2)/6)-1) = ?/2
44.99% of 499.98 × (3.30/7.40)% of 1399.97 + 10.02 = ?
What will come in the place of question mark (?) in the given expression?
7 X 18 + ? = (52 - 6) X 9
(√1024 + √324)% of 780 = ?% of 260
