Question
Ajay invested Rs.a in SI at 7% rate of interest per
annum for 12 years. Vishal invested the same amount in SI at 5% rate of interest per annum for 8 years and the difference between the interest obtained by Ajay and Vishal is Rs.2200. Find the amount invested by Vishal.Solution
According to question, => (a × 7 × 12)/100 – (a × 5 × 8)/100 = 2200 => 84a/100 – 40a/100 = 2200 => 44a/100 = 2200 => a = Rs.5000
2945 – 1508 + 3454 = ? + 2255
13/3 – (23/6) = ? – (22/9)
2(1/3) + 2(5/6) – 1(1/2) = ? – 6(1/6)
What will come in the place of question mark (?) in the given expression?
√1936 + (84 ÷ 2 × 1.5) – 35² + 18² = ?
1440 ÷ 12 + 540 ÷ √36 + ? = 180 * 3
(√7225 x √1225)/(√625) = ?
(1520 - 1350) ÷ (550 – 500) = ?
