A certain sum of money will be doubled in 4 years at the rate of simple interest percent per annum is:
SI = (P × R × T)/100 Amount, (A) = P + SI Let P be the principal. SI = 2P – P = P ⇒ P = (P × R × T)/100 ⇒ P = (P × R × 4)/100 ⇒ R = 100/4 = 25%
√10201 × √3969 - (52)² = √? + (60)²
...1090 + 237 + 30549 - 86 - 104 = ? x 6
4567.89 - 567.89 - 678.89 = ?
(? × 3)2 - 85 = 115 × 5 + 69
181/8 + 51/4 – 63/8 = ? + 9/2
26 2 – 13% of 400 + (529 ÷ 23 2 ) = ? 2
(750 / 15 × 15 + 152 + 20% of 125) = ?3
(1748 ÷ 8) + 76.8 × 35 =(? × 4) + (42 × 35.5)
((12+12+12+12)÷4)/((8+8+8+8+8+8)÷16) = ?
