A person invest some amount in a business into 2 parts. If he invest 1st part at 8% for 3 years and 2nd part invest at 7(1/2)% p.a. for 4 years. Total Simple Interest from both instalment is Rs. 2262. If 2/5th of the sum of first investment is equal to 3/7 times of the 2nd investment. Find the sum (principal) of each part?
P₁ × 2/5 = P₂ × 3/7 P1/P2= 15/14 P₁ : P₂ = 15 : 14 Then P₁ = 15x and P₂ = 14x Sum of Simple Interest of both is 2262 i.e. (15x × 8 ×3)/100 + (14x ×15 ×4)/(2 ×100)=2262 Now 7.8 x = 2262 So, x = (2262/78) × 10 = 290 Therefore, Sum invest in 1st Part = 290 × 15 = Rs. 4350 Sum invest in 2nd part = 290 × 14 = Rs. 4060
2(1/3) + 2(5/6) – 1(1/2) = ? – 6(1/6)
63- [22-{24 ÷ 3-(9-15 ÷ 5) ÷ 6}]=?
1000÷ 250 = ( 3√? × √1444) ÷ ( 3√512 × √361)
(〖(0.4)〗^(1/3) × 〖(1/64)〗^(1/4) × 〖16〗^(1/6) × 〖(0.256)〗^(2/3))/(〖(0.16)〗^(2/3) × 4^(-1/2) ×〖1024〗^(-1/4) ) = ?
(3500 ÷ √1225) × √(20.25) = ? ÷ 4
√ 225 x 24 - √ 144 x 18 = ?
[123 ÷ 8 ÷ 9] × 144 = ? + 12 × 5
[(36 × 15 ÷ 96 + 19 ÷ 8) × 38] = ?% of 608
2/5 of 3/4 of 7/9 of 14400 = ?
(√196 + √121) × 4 = ?/2
